The document summarizes the design of beam-and-slab systems. It describes how the one-way slab is designed as a continuous slab spanning the beam supports using moment distribution methods or a simplified coefficient method. Interior beams are designed as T-beams and edge beams as L-beams, which provide greater flexural strength than conventional beams. The beam and slab must be securely connected to transfer shear forces between them. The slab is reinforced as a one-way system and the beams are designed as simply supported beams spanning their supports.
This document discusses the design of two-way slabs. It defines a two-way slab as having a ratio of long to short spans of less than 2. The main types of two-way slabs described are flat slabs with drop panels, two-way slabs with beams, flat plates, and waffle slabs. The basic steps of two-way slab design are outlined, including choosing the slab type and thickness, the design method, calculating moments, determining reinforcement, and checking shear strength. Two common design methods are described: the direct design method which uses coefficients, and the equivalent frame method which analyzes frames cut between 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
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.

Development of M-φ curves and diagrams are covered.

The document discusses the historical background and advantages of the strength design method for reinforced concrete structures. It provides details on how structural safety is assured through factored loads and reduced material strengths. Key aspects of the strength design method covered include derivation of expressions for beam design, minimum and balanced steel ratios, requirements for under-reinforced and over-reinforced beams, and minimum thickness and deflection requirements.
The document discusses the design of doubly reinforced beams using the limit state method. It defines singly and doubly reinforced beams, notes the need for doubly reinforced beams, and provides the minimum and maximum percentages of compression steel allowed in beams. It also states the assumed yield stress for compression steel and describes the strain diagram and stress distribution in a doubly reinforced beam. The process of analyzing and designing a doubly reinforced beam is outlined as choosing the depth of the neutral axis, calculating the tension in steel and compression in steel, and checking if the assumed neutral axis satisfies equilibrium.
The document describes the process used by a structural analysis program to design concrete beam flexural reinforcement according to BS 8110-97. The program calculates reinforcement required for flexure and shear. For flexural design, it determines factored moments, calculates reinforcement as a singly or doubly reinforced section, and ensures minimum reinforcement requirements are met. Design is conducted for rectangular beams and T-beams under positive and negative bending.

This document describes how to draw the influence lines for the force in member GF and member FC of a truss. It first shows the truss and then provides the steps to calculate the influence lines when a unit load is placed at different positions on the truss members AB, BC, and CD. The influence lines are drawn based on the calculated forces in GF and FC as the load moves along each member.
This document provides lecture notes on trusses and truss analysis. It defines a truss as consisting of straight members connected at joints, with no member continuous through a joint. Simple trusses follow the rule that the number of members m equals 2n-3, where n is the number of joints. The document describes two common methods for truss analysis: (1) the method of joints, which uses equilibrium equations at each joint to solve for member forces, and (2) the method of sections, which uses equilibrium of a portion of the truss cut out by a section. Sample problems demonstrate applying each method to determine member forces in specific trusses.

Structural analysis is the process of determining how systems of forces and moments act upon structures such as buildings and bridges. Engineers use structural analysis to understand how external and internal forces are distributed throughout a structure, and how components will react to these forces. The goal of structural analysis is to ensure a structure can withstand expected forces without failing or experiencing excessive deformation.
The document discusses the misuse of rubblization, which involves breaking up existing concrete slabs, as a rehabilitation technique for concrete pavements. It argues that rubblization destroys structural integrity, does not address the root causes of deterioration, and can exacerbate problems. Alternatives like concrete pavement restoration (CPR) and concrete overlays directly repair isolated distress and maintain the pavement's strength. While rubblization may be appropriate when a pavement has severe material problems, its performance is generally poor. Concrete overlays and CPR are more effective and economical rehabilitation options in most cases.
