This document discusses three common types of supports in structures: roller supports, fixed supports, and pinned supports. Roller supports can resist vertical forces but not horizontal forces. Fixed supports are the most rigid and constrain movement in all directions. Pinned supports allow rotation but not translation, similar to a hinge. Each type has different applications and limitations depending on the structural needs.

Beam and its types
This document describes different types of beams based on their end support, cross-section shape, equilibrium condition, and geometry. Beams can be simply supported, continuous, overhanging, cantilever, fixed, or trussed based on their end support. Their cross-section can be I-beams, T-beams, or C-beams. Based on equilibrium, beams are either statically determinate or indeterminate. A beam's geometry can be straight, curved, or tapered.
Types of support
The document discusses different types of supports and loads that can act on beams. It describes:
1) Types of supports including simple, roller, hinged, and combinations that determine reaction forces and the beam's equilibrium.
2) Types of loads such as concentrated point loads, uniformly distributed loads, and varying loads which can be represented as a single load at the center.
3) Examples of calculating support reactions and internal forces in beams under different loading conditions.
Types of beam & types of supports
This document discusses different types of beams and supports used in engineering mechanics. It describes four types of supports - fixed, simple, roller, and hinged - based on how they restrict the movement of beams. It also outlines six types of beams defined by their support conditions: fixed, cantilever, simply supported, overhanging, continuous, and combinations of these. Finally, it categorizes loads as point, uniformly distributed, or uniformly varying based on how forces are applied along the beam.
Steel connections
Connections are critical structural elements that join members in steel structures. Common connection types include bolted, welded, and bolted-welded combinations. Connections are classified based on the connecting medium, type of forces transmitted, and elements joined. Riveted connections were previously common but have been replaced by bolted connections which are faster and cheaper to install. Welded connections provide rigidity but require careful design to avoid cracking. Modern connections often combine bolting and welding for strength and economy. Shear and moment connections behave differently in transmitting forces between members like beams and columns. Proper connection design is important for structural integrity and safety.
Rivet connection
This document discusses riveted connections in steel structures. It describes the different types of rivets, including their shape and method of installation. Some key types are snap headed rivets, pan headed rivets, and flat counter sunk rivets. It also outlines the advantages and disadvantages of riveted connections. Advantages include ease of installation without electricity, while disadvantages include noise and required skilled labor. The document further explains different riveted joint configurations, including lap joints and butt joints, providing examples of single and double riveted versions of each. Finally, it briefly outlines potential failure modes of riveted connections, such as shear failure of rivets or plates, and bearing failure of plates or
Bolted connections
This document discusses bolted connections used in structural engineering. It begins by explaining why connection failures should be avoided, as they can lead to catastrophic structural failures.

Design of columns as per IS 456-2000
This document discusses reinforced concrete columns. It begins by defining columns and different column types, including based on shape, reinforcement, loading conditions, and slenderness ratio. Short columns fail due to material strength while slender columns are at risk of buckling. The document covers column design considerations like unsupported length and effective length. It provides examples of single storey building column design and discusses minimum longitudinal reinforcement requirements in columns.
Two way slab
A two way slab is supported by beams on all four sides and has a ratio of longer to shorter span of less than 2. It has reinforcement in both directions. The design process involves preliminary sizing based on deflection criteria, analysis, sizing of reinforcement in the shorter direction as a singly reinforced section, checking for shear and deflection, and detailing of reinforcement including development length and torsion reinforcement.
Base isolation
Base isolation is a seismic protection system that separates a structure from its foundation, allowing the structure to remain largely motionless during an earthquake by absorbing shock through devices like friction pendulums and elastomeric bearings. There are various types of base isolators including low-damping rubber bearings, lead-rubber bearings, and sliding systems. Base isolation is most suitable for low to medium-rise buildings founded on firm soil, as it reduces seismic forces and prevents damage by permitting the ground and structure to move independently.
Ductile detailing
This document discusses ductile detailing of reinforced concrete (RC) frames according to Indian standards. It explains that detailing involves translating the structural design into the final structure through reinforcement drawings. Good detailing ensures reinforcement and concrete interact efficiently. Key aspects of ductile detailing covered include requirements for beams, columns, and beam-column joints to improve ductility and seismic performance. Specific provisions are presented for longitudinal and shear reinforcement in beams and columns, as well as confining reinforcement and lap splices. The importance of cover and stirrup spacing is also discussed.
Foundation and its types
The document discusses different types of foundations for buildings. It describes shallow foundations, which transfer loads to depths of less than 3 meters, including spread footings, strip foundations, mat foundations, and combined footings. It also describes deep foundations, which transfer loads to depths greater than 3 meters, including pile foundations and caisson foundations. Key factors for determining the appropriate foundation type include the soil bearing capacity and required load capacity of the structure.
Types of isolated footing and design
Footings are structural members that support columns and walls and transmit their loads to the soil in a way that does not exceed the soil's load bearing capacity or cause excessive settlement or rotation. There are two main types of isolated column footings: pad footings and sloped footings. The design process for isolated footings includes determining the size, net upward pressure, bending moment, depth, reinforcement, and load transfer requirements. The example provides specifications to design an isolated square footing to support a 400mm x 400mm column with an axial load of 800kn using M-20 concrete and Fe-250 steel, accounting for a soil bearing capacity of 120kn/m2.
Columns
This document discusses different types of columns used in construction. It defines a column as a structural member subjected to compressive axial loads. Columns are classified as long, short, or intermediate based on their length-to-minimum radius of gyration ratio. Long columns have a ratio greater than 50, short columns less than 15-50, and intermediate between 30-100. The document provides examples of column types and discusses effective length, radius of gyration, buckling load, and Euler's formula for calculating crippling load.

Steel structures
Steel structures involve structural steel members designed to carry loads and provide rigidity. Some famous steel structures include the Walt Disney Concert Hall, Tyne Bridge, and Howrah Bridge. Steel structures have advantages like high strength, ductility, elasticity, and ease of fabrication and erection. The Howrah Bridge is a steel cantilever bridge that connects Howrah and Kolkata. When built, it was the 3rd longest cantilever bridge in the world. It uses steel components like I-beams, rivets, and expansion joints and was constructed between 1936-1942.
Shallow foundation
Shallow foundations are foundations where the depth is equal to or less than the width. There are four main types of shallow foundations: 1) Spread footings which spread loads over a larger area and are used for light loads or strong soils, 2) Combined footings which are preferred when columns are close together to make construction more economical, 3) Strap or cantilever footings which connect independent footings with a beam that does not transfer pressure to the soil, and 4) Mat or raft foundations which cover the entire area beneath a structure and are used for supporting loads on soft soils by spreading them over a large area.

What is a Slab?
Slabs are the one of the most widely used structural elements whose depth is considerably smaller than rest of the dimensions. Basically slabs are used as roofs and floors in buildings, roof and bottom on water tanks, on bridges etc.
Slabs support and transfer load i.e. Dead load and live load, to columns by shear, flexure, and torsion. Slabs also help in reducing the effects of lateral wind loads and earthquake loads.
What is One Way Slab?
One way slabs are the slabs in which most of the loads are carried on the shorter span. The ratio of longer span to shorter span is equal to or greater than two or when the slab is supported by beams only along two opposite sides slab then the slab behaves as a One-way slab.
What is Two Way Slab?
Two-way slabs are the slabs in which loads are carried on both of the spans. The ratio of longer span to shorter span is less than two and when the slab is supported by beams along all the sides then the slab behaves as a two-way slab.

It emphasizes designing key structural elements like beams and columns to be ductile to absorb energy and prevent collapse during earthquakes. Shear walls are also discussed as important seismic resistant elements.
Civil Engineering (Beams,Columns)
The superstructure of a building consists of elements above the foundation like beams, columns, lintels, roofing and flooring. Beams are horizontal members that carry loads and transfer them to columns or walls. Reinforced concrete beams are designed to resist both bending moments and shear forces from loads. There are different types of beams like simply supported, fixed, cantilever, continuous and overhanging beams which are designed based on how they are supported. Columns are vertical load bearing members that transfer loads from beams and slabs to the foundation. Common column types include long, short and intermediate columns. Lintels are short horizontal members that span small openings like doors and windows and transfer loads to masonry, steel or reinforced concrete

Earth 0205-response spectrum
The document discusses response spectra, which are plots of the maximum response of single-degree-of-freedom oscillators versus their natural period when subjected to a specific ground motion. Response spectra allow characterization of earthquake ground motions and are commonly used in earthquake-resistant design. The analysis procedure using response spectra involves obtaining the spectral acceleration from the response spectrum curve based on an oscillator's period and calculating the maximum displacement, base shear, and overturning moment. This procedure can be extended to multi-degree-of-freedom structures. An example is provided to demonstrate using a response spectrum to determine interstory drifts and story shears in a two-story building.

Base isolation topic as per jntu syllabus for m.tech 1st year structures
Base isolation is a seismic protection system that places flexible bearings between a structure and its foundation. During an earthquake, the bearings allow the structure to move independently from the shaking ground, isolating it from seismic forces. Common base isolation bearings include elastomeric bearings and lead-rubber bearings, which are stiff vertically but flexible horizontally. Base isolation is effective because it lengthens a structure's period of vibration, reducing the accelerations and forces experienced, and protects both the structure and its contents from earthquake damage.

Base isolation techniques-Earthquake Engineering
The document discusses base isolation techniques for earthquake-resistant building design. Base isolation involves separating the structure from its foundation using a suspension system to reduce seismic demand on the building. There are several types of base isolation devices that provide flexibility, damping and resistance to vertical loads, including elastomeric bearings, lead rubber bearings, and flat or curved slider bearings. Elastomeric bearings use layers of rubber between steel plates to support vertical loads while allowing flexibility under lateral earthquake forces.
Base isolation

Chapter 7
Bearings are structural devices between the bridge superstructure and substructure that transmit loads and accommodate movements. There are two main types of bearings: fixed bearings that are fixed against translation but allow rotation, and expansion bearings that allow both translation and rotation. Selection depends on factors like superstructure type, substructure supports, and span length. Bearings are important components that require careful design, skilled construction, and regular maintenance to prevent failures inducing high stresses. Common bearing types include sliding plate, roller, rocker, elastomeric, and lead rubber bearings. Railings along bridge edges protect traffic and pedestrians, and come in traffic, pedestrian, and combination varieties depending on the bridge use and design speeds.

It provides details on spring materials, manufacturing processes, and key spring terminology.
Arches - Form Active Structure System
Form active structure systems utilize curved structures like arches to carry loads across gaps primarily through compression. Arches distribute loads through their curved shape, reducing stresses compared to rigid connections. Key factors in arch design include the rise-to-span ratio to minimize thrust, and the shape which affects cost, stresses, and load distribution. Arches can fail through rotation, sliding at supports, or crushing under high compression, and are reinforced or redesigned to address failure modes. Early arched structures gained stability through added weight and convenient construction shapes, while Gothic cathedrals demonstrated advanced vaulting techniques.
Arch System
Arch is a curved structure designed to carry loads across a gap mainly by compression. The mechanical principle of the arch is precisely the same as that of the portal frame. The straight pieces of material joined by sharp bends are smoothed into a continuous curve. This increases the cost of construction but greatly reduces the stresses.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Types of supports in structures
- 1. Name : Ahmed Gamal Gouda Gaballah ID : 20141178 Group : 2 Eng : Mohamed Fahmy About : Types of supports in structures
- 2. Types of Supports:- 1-Roller Supports:- can resist a vertical force but not a horizontal force. A roller support or connection is free to move horizontally as there is nothing constraining it. Application: The most common use of a roller support is in a bridge. In civil engineering, a bridge will typically contain a roller support at one end to account for vertical displacement and expansion from changes in temperature. This is required to prevent the expansion causing damage to a pinned support. Limitations: This type of support does not resist any horizontal forces. This obviously has limitations in itself as it means the structure will require another support to resist this type of force.
- 4. 2- Fixed Support:- A fixed support is the most rigid type of support or connection. It constrains the member in all translations and rotations (i.e. it cannot move or rotate in any direction). The easiest example of a fixed support would be a pole or column in concrete. The pole cannot twist, rotate or displace; it is basically restricted in all its movements at this connection. Application: Fixed supports are extremely beneficial when you can only use a single support. The fixed support provides all the constraints necessary to ensure the structure is static. It is most widely used as the only support for a cantilever. Limitations: Fixed supports offer absolutely no 'give'. In a sense, its greatest advantage can also be its downfall, as sometimes a structure requires a little deflection or 'play' to protect other surrounding materials. For instance, as concrete continues to gain its strength it also expands. So if a support is not designed correctly the expansion could lead to a reduction in durability.
- 6. 3- Pinned Support :- A pinned support is a very common type of support and is most commonly compared to a hingein civil engineering. Like a hinge, a pinned support allows rotation to occur but no translation (i.e. it resists horizontal and vertical forces but not a moment). Think of your elbow; you are able to extend and flex the elbow (rotation) but you cannot move your forearm left to right (translation). Application: Pinned supports can be used in trusses. By linking multiple members joined by hinge connections, the members will push against each other; inducing an axial force within the member. The benefit of this is that the members contain no internal moment forces, and can be designed according to their axial force only. Limitations: A single pinned support cannot completely restrain a structure, as you need at least two supports to resist the moment.
