The document defines a truss as a rigid structure composed of two force members connected at joints. There are three types of trusses: perfect trusses which have just enough members to remain stable under loading, deficient trusses with too few members, and redundant trusses with excess members. The key assumptions in truss analysis are that members are pin jointed and carry only axial forces, and trusses are loaded at joints. Two common methods to analyze trusses are the method of joints, which determines member forces by analyzing joints individually, and the method of sections, which analyzes equilibrium across a cut through selected members. Several example problems demonstrate applying these analysis methods to various truss configurations.

Trusses and its applications

A truss is a structure composed of straight members connected at joints that forms a stable structure. There are three types of trusses: perfect trusses which have just enough members for equilibrium, deficient trusses with fewer members that change shape under load, and redundant trusses with extra members that maintain shape under load. Truss analysis involves applying equilibrium equations to sections or joints of the truss to determine member forces. Trusses are commonly used in roofs, bridges, and other engineering structures.

Design and analysis of slabs

This document provides an overview of analysis and design methods for concrete slabs, including:
1. Elastic analysis methods like grillage analysis and finite element analysis can be used to determine moments and shear forces in slabs.
2. Yield line theory is an alternative plastic/ultimate limit state approach for determining the ultimate load capacity of ductile concrete slabs. It involves assuming yield line patterns that divide the slab into rigid regions and equating external and internal work.
3. Examples are provided to illustrate yield line analysis for one-way spanning slabs and rectangular two-way slabs. Conventions, assumptions, and calculation procedures are explained.

Design of torsion reinforcement

Because of torsion, the beam fails in diagonal tension forming the spiral cracks around the beam. Warping of the section does not allow a plane section to remain as plane after twisting. Clause 41 of IS 456:2000 provides the provisions for
the design of torsional reinforcements. The design rules for torsion are based on the equivalent moment.

determinate and indeterminate structures

This topic I am uploading here contains some basic topics in structural analysis which includes types of supports, reactions for different support conditions, determinate and indeterminate structures, static and kinematic indeterminacy,external and internal static indeterminacy, kinematic indeterminacy for beams, frames, trusses.
need of finding indeterminacy, different methods available to formulate equations to solve unknowns.

Introduction to prestressed concrete structures

Prestressed concrete combines high-strength concrete and high-strength steel in an active manner by tensioning steel tendons and holding them against the concrete, putting it into compression. This transforms concrete from a brittle to a more elastic material. It allows for optimal use of each material's properties and better behavior under loads. Prestressed concrete was pioneered in the 1930s and its use has expanded, finding applications in bridges and other structures. Common methods are pretensioning and post-tensioning, using various tendon types, with bonded or unbonded configurations. Tensioning is done using mechanical, hydraulic, electrical or chemical devices.

Truss

In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object".

7 losses in prestress

Prestress loss occurs as prestress reduces over time from its initial applied value. There are two types of prestress loss - immediate losses during prestressing/transfer and long-term time-dependent losses. Immediate losses include elastic shortening, anchorage slip, and friction. Long-term losses include creep and shrinkage of concrete and relaxation of prestressing steel. The quantification of losses is based on strain compatibility between concrete and steel. For a pre-tensioned concrete sleeper, the percentage loss due to elastic shortening was calculated to be approximately 2.83% based on the stress in concrete at the level of the tendons.

Influence line

This document discusses influence lines for beams. Influence lines graphically show how a unit load moving across a structure affects structural responses like reactions, shears, moments, and deflections. The ordinates of an influence line diagram represent the magnitude and type of a structural response when a unit load is at that point. Influence lines are useful for analyzing the effects of moving loads on structures. They can be used to determine locations of loads that cause maximum structural responses, which can then be calculated. The document also provides properties of influence lines and discusses how to qualitatively and quantitatively draw them for beams.

Analysis of Truss

Analysis of Truss, There are two major methods of analysis for finding the internal forces in members of a truss; the Method of Joints, which is typically used for the case of creating a truss to handle external loads, and the Method of Sections, which is normally used when dealing modifying the internal members of an existing truss.

This document provides details about the construction of a cable-stayed bridge in Bardhaman, India. The bridge has a main span of 124 meters and side spans of 64.5 meters. It is constructed with precast concrete segments and steel pylons that are 62 meters high. The bridge construction involves casting piers and segments, erecting the steel pylons and towers, and then incrementally launching the concrete segments and installing the stay cables to complete the bridge deck.

Design of columns biaxial bending as per IS 456-2000

This document discusses the design of compression members subjected to axial load and biaxial bending. It introduces the concept of biaxial eccentricities and explains that columns should be designed considering possible eccentricities in two axes. The document outlines the method suggested by IS 456-2000, which is based on Breslar's load contour approach. It relates the parameter αn to the ratio of Pu/Puz. Finally, it provides a step-by-step process for designing the column section, which involves determining uniaxial moment capacities, computing permissible moment values from charts, and revising the section if needed. It also briefly mentions the simplified method according to BS8110.

Betti

1. Betti's theorem from 1872 states that for linear elastic structures under two sets of forces P and Q, the work done by P through displacements caused by Q is equal to the work done by Q through displacements caused by P.
2. An example is given of a beam with two points where a force P is applied to point 1, displacing point 2, and then a force Q is applied to point 2. Betti's theorem says the work is equal in both cases.
3. The Maxwell-Betti reciprocal theorem extends this idea and is illustrated using a simply supported beam with two load points.

Prestressed composite beams

The document discusses composite construction using precast prestressed concrete beams and cast-in-situ concrete. It describes how the two elements act compositely after the in-situ concrete hardens. Composite beams can be constructed as either propped or unpropped. Propped construction involves supporting the precast beam during casting to relieve it of the wet concrete weight, while unpropped construction allows stresses to develop under self-weight. Design and analysis of composite beams involves calculating stresses and deflections considering composite action. Differential shrinkage between precast and in-situ concrete also induces stresses.

Balanced section,under reinforced,over reinforced section

Here we discussed about the balanced section,Under reinforced and Over reinforced sections and what are the failure and their moment of resistance.. and also comparison between among three sections

Design of footing as per IS 456-2000

The document discusses the design of footings for structures. It begins by explaining that footings are needed to transfer structural loads from members made of materials like steel and concrete to the underlying soil. It then describes different types of shallow and deep foundations, including spread, strap, combined, and raft footings. The document provides details on designing isolated and combined footings to resist vertical loads and moments based on provisions in IS 456. It also discusses wall footings and combined footings that support multiple columns. In summary, the document covers the purpose of footings, various footing types, and design of isolated and combined footings.

Bar bending schedule (2)

Bar Bending Schedule (BBS) is used to calculate the total steel required for building construction. It organizes reinforcement bars by structural element and provides details like bar location, marking, size, quantity, and shape. BBS has evolved over time with taller buildings, increased steel usage, and outdated recommendations. A BBS example is provided for a column, calculating bar requirements and properties like cutting length, total length, and weight based on standards. Proper BBS preparation helps estimate costs, improve construction quality, and minimize steel waste.

Yield line theory

Yield line theory is an analysis approach for determining the ultimate load capacity of reinforced concrete slabs. It was pioneered in the 1940s and is closely related to plastic collapse analysis of steel frames. It assumes ductile behavior where yield lines form that allow further rotation without additional moment. Yield line analysis is allowed by some codes if the ratio of crack spacing to depth is low. Advantages are it is simpler than elastic analysis and gives ultimate capacity rather than just yield load, while disadvantages are it requires understanding likely failure mechanisms and may allow dangerous designs without further checking.

Trusses Method Of Sections

The document discusses methods for analyzing statically determinate truss structures, including the Method of Joints and Method of Sections. It uses the example of a truss bridge in Brockport, NY to demonstrate these methods. The Method of Sections involves cutting the truss into rigid bodies and applying equilibrium equations to solve for member forces. Reactions can first be found using the Method of Joints, then sections are cut to solve for internal forces.

Structural Analysis (Solutions) Chapter 9 by Wajahat

The document provides information about determining displacements of joints in truss structures using the method of virtual work and Castigliano's theorem. It includes the geometry, applied forces, and cross-sectional areas of sample truss problems. The user is asked to determine the vertical displacement of various joints by calculating the internal virtual work of the truss members. Solutions are provided using both the virtual work method and Castigliano's theorem.

Method of joints

This document summarizes key concepts from a chapter on analyzing structures. It discusses how to determine the internal and external forces acting on trusses, frames, and machines. The objectives are to calculate the forces carried by various structures and determine if they can withstand these forces. It describes analyzing trusses using the method of joints and method of sections. Frames are introduced as structures with multi-force members. The document also distinguishes between determinate and indeterminate structures, with determinate structures having solvable equilibrium equations and indeterminate structures lacking sufficient equations.

Truss examples

1) The documents provide examples of solving for forces in truss members by using free body diagrams and equilibrium equations.
2) The solutions involve drawing FBDs of the trusses or sections of trusses, then writing the ΣF and ΣM equations and solving the systems of equations.
3) The determined forces are then identified as either tension or compression forces in the members.

Types of truss, substitute member

The document classifies and describes different types of trusses. Simple trusses are made of basic triangular elements connected by additional members. Compound trusses connect two or more simple trusses together using common joints or connecting members. Complex trusses cannot be classified as simple or compound; their equilibrium equations cannot be uncoupled. The document provides an example of analyzing a complex truss using the method of substitute members.

Structural analysis (method of sections)

The method of sections can be used to determine member forces in a truss. It involves cutting or sectioning the truss and applying equilibrium equations to the cut parts. For example, a truss can be cut through members to determine the forces in those members by drawing and analyzing the free-body diagram of each cut section. Either the method of joints or method of sections can be used to analyze trusses.

connections in steel structure

The document discusses different types of connections used in steel structures. It describes connections as structural elements that join members like beams and columns. The main types of connections discussed are riveted, bolted, and welded connections. Riveted connections use round steel bars called rivets with heads on both ends. Bolted connections fasten members together using bolts that can be loaded in tension, shear, or both. Welded connections primarily join members using welds, with groove welds being the most reliable. The document provides advantages and disadvantages of each type of connection and notes that connections allow the different steel members to function as a single composite unit.

Trusses The Method Of Sections

The document discusses different types of structures and methods for analyzing trusses. Trusses are structures made of straight members connected at joints. Two common methods for analyzing trusses are the method of joints and method of sections. The method of joints involves drawing force diagrams at each joint and applying equilibrium equations. The method of sections involves cutting a truss and analyzing one side of the cut section. Zero-force members, which carry no load, can be identified and removed to simplify analysis.

Connections

This document discusses riveted connections and their design. It covers the different types of riveted joints like lap joints and butt joints. It provides specifications for riveted connections like the gross diameter of rivets, gauge, pitch and edge distance. It also discusses the types of failures in riveted connections and how to calculate the strength of riveted joints based on the strength of rivets in shear and bearing and the strength of plates in tension. The efficiency of riveted joints is defined. Examples of calculating rivet values are also provided.

Shear Force And Bending Moment Diagram For Frames

This document discusses analyzing shear and moment diagrams for frames. It provides procedures for determining reactions, axial forces, shear forces, and moments at member ends. Examples are given of drawing shear and moment diagrams for simple frames with different joint conditions, including pin and roller supports. Diagrams for a three-pin frame example are shown.

trusses

This document discusses various types of trusses and methods for analyzing truss structures. It begins by describing common types of trusses used in roofs and bridges. It then covers topics such as classifying trusses as simple, compound, or complex, and determining their stability and determinacy. The document introduces analytical methods like the method of joints and method of sections for calculating member forces in statically determinate trusses. It provides examples of applying these methods to solve for unknown member forces.

Roof trusses

This document discusses roof trusses, including their components, designs, fabrication, installation, and safety. It covers truss types, principles of design, how they are assembled using metal connectors, how they provide structure and span for roofs, and how to properly install and brace trusses. Safety measures are emphasized, such as using fall protection when working on trusses.

types and effect of loads

1. Shear walls are structural elements used to resist lateral/horizontal/shear forces parallel to the plane of the wall through cantilever or truss action.
2. For bridges and tall buildings, stresses should be calculated for the most severe combinations of loads including dead, live, wind, seismic and temperature loads.

An introduction to the module is given, including forces, moments, and the important concepts of free-body diagrams and static equilibrium. These concepts will then be used to solve static framework (truss) problems using two methods: the method of joints and the method of sections.Trusses

Trusses are structures composed of straight members connected at joints. They are used to support roofs and bridges. Trusses can only experience axial loads and moments are excluded. To determine the forces in each member, assumptions are made including that loads only act at end points. The internal forces are calculated using methods like the joints method where equilibrium is applied at each node. For example, in one truss problem the reactions were first calculated and then equilibrium was applied at each node to determine the tensions and compressions in each member.

Trusses

Trusses are structures composed of straight members connected at joints. They have three key characteristics: they only experience axial loads, loads are applied only at end points, and members are joined by pins. Trusses are used to support roofs and bridges. To analyze a truss, assumptions are made that loads act only at end points, member weight is ignored, and members experience only axial loads as either tension or compression. The method of joints and method of sections can be used to calculate the internal forces in each member and determine if each member experiences tension or compression.

It focuses on plane trusses, which are frameworks composed of members joined at their ends to form a rigid structure. The two main methods discussed for analyzing truss forces are the method of joints, which satisfies equilibrium conditions at each joint, and the method of sections, which analyzes equilibrium across a cut section. Key assumptions made in truss analysis are that members only experience two internal forces and connections act as pin joints.

TRUSS ANALYSIS (TERM PAPER REPORT)

This document provides an introduction and overview of truss analysis. It defines a truss and describes the key assumptions made in truss analysis, including that loads act only at joints and member weights are negligible.

Truss problems

This document discusses methods for analyzing forces in perfect trusses, including the method of joints and method of sections. It provides examples of applying each method to determine the magnitude and nature of forces in various truss members. It also defines the concepts of virtual work and the principle of virtual work, which states that the algebraic sum of virtual works done by all forces in equilibrium is zero. This allows determining unknown forces by considering small imaginary displacements.

This document summarizes a study on the seismic response of reinforced concrete frames with varying numbers of bays and storeys. Three frame configurations - 3 bay, 5 bay, and 7 bay with 9 stories each - were modeled and analyzed under gravity and seismic loads. Both prismatic frames and frames with non-prismatic elements like stepped beams and haunches at beam-column joints were considered. The effects of variables like haunch size, beam inertia, and live load patterns on internal forces and storey drift were examined. Key results showed that non-prismatic elements can reduce bending moments and axial forces compared to conventional prismatic frames.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT

The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

- 1. TRUSS Page 1 CHAPTER 4 TRUSS CONTENT OF THE TOPIC: Definition of truss Types of truss Perfect Truss Imperfect Truss Deficient Truss Redundant Truss Assumption made for the analysis of truss Analysis of truss Types of methods of analysis Method of joint Method of section and Graphical method Problems on Method of joint and Method of section Definition of Truss: A truss is defined as a system of two force members connected in such a way that a rigid structure is formed. Truss is made up of two force members. Types of Trusses:
- 2. TRUSS Page 2 Perfect Truss: A perfect truss is that, which is made up of members just sufficient to keep it in equilibrium, when loaded, without any change in its shape. Such structure satisfies following equation. n = 2j-3 where, n = number of members j = number of joints Eg. Basic Perfect Truss Here n = 3 and j = 3 3 = (2 x 3) – 3 3= 3 Perfect Truss Here n = 5 and j = 4 5 = (2 x 4) – 3 5= 5 Deficient Truss: In such truss the numbers of members are less than (2j-3). Such trusses are unable to carry any loads. So such trusses are unstable which undergo deformation. Eg. Here n = 4 and j = 4 4 = (2 x 4) – 3 4 < 5 Where, δ is lateral displacement Redundant Truss: In such truss the numbers of members are more than (2j-3). In such trusses the members are more than required which is sufficient to carry loads. They don’t undergo any deformation.
- 3. TRUSS Page 3 Eg. Here n = 6 and j = 4 6 = (2 x 4) – 3 6 > 5 Member: The straight component bars of the trusses joined at the ends by the pins are known as members. Two force member: When a member is subjected to no couples and forces are applied at only two ends of the member is called as two force member or two point force member. Arrow away from joints Arrow towards the joints or or Arrow facing towards each other Arrow away from each other Frame: A frame is structure of combination of two force members and three force members or multi-force members as shown in Fig. 2. Figure 2
- 4. TRUSS Page 4 Assumption made for the analysis of truss 1) All the members are pin jointed. 2) All the members are assumed to two force members. 3) The truss is loaded at the joints only. 4) The self weight of the truss is considered as negligible in comparison with the other external forces acting on a truss. 5) The cross section of the members of trusses is uniform. Analysis of Truss: To analyze a truss is nothing but a determination of the reactions at the supports and the forces in the members of the frame. STEPS FOR MEHOD OF JOINTS AND MEHOD OF SECTION: Method of Section: 1) When the forces in all members of a truss are to be determined, then the Method of Joint is useful. 2) Calculate the support reactions for external loading acting on the truss. 3) Then find the forces in the members by joint by joint. a. Select a joint, in such a way that it will have only two unknown members (i.e. forces in the two members of a truss have to find). b. We have to select only two unknowns at every joint because we are available with only two equations (∑FY = 0 and ∑FX = 0). c. Initially assume all the unknown forces in the members of a truss as tensile. After calculation of force, if the calculated value in any of the member is negative then it reveals that the assumed direction or sense in that member is wrong; in that case change the sense. (i.e. if assumed direction is tension, then make it as compression and vice versa, in F.B.D. and calculate the force in other member by considering the changed sign. Repeat the same procedure for other joints). 4) Prepare a table showing member, magnitude and sense of force of each member of a truss. Method of Section: 1) When the forces in a few members of a truss are to be determined, then the Method of Section is mostly used. 2) Calculate the support reactions for external loading acting on the truss. 3) In this method, a section line is passed through the members, in which forces are to be determined.
- 5. TRUSS Page 5 4) The section line should be passed in such a way that, it does not cut more than three members in which forces are unknown because we are available with three equations ∑M = 0, ∑FY = 0 and ∑FX = 0. 5) If force in the members BC, GC and GF i.e. FBC, FGC, and FGF respectively we want to calculate. Then pass a section line 1-1 through these members. 6) The part of the truss, on any one side of the section line, is treated as a free body in equilibrium under the action of external forces on that part and forces in the members cut by the section line. See Fig. (1) and (2). (We have to select the LEFT or RIGHT part of the truss in such a way that, it will contain less geometry and external loads acting on the truss). Fig.1 Fig.2 7) The unknown forces in the members are then calculated by using the equations of equilibrium. ∑M = 0, ∑Fy = 0 ∑FX = 0
