Chapter 5
Analysis of Sections
5.1 Introduction
The term ‘analysis’ in the context of structural design refers to determination of stresses in materials (or deflections, crack widths etc.) and finding the ultimate capacity of the section (in flexure, shear, torsion etc.). In order to find the stress or ultimate capacity, the cross-sectional details (including the area of steel) and the properties of materials should be known to begin with.
This chapter deals with the determination of flexural stress and ultimate moment capacity of the section. For this, three basic equations of mechanics are used.
- Equilibrium equations
- Constitutive relations
- Compatibility conditions
Equilibrium Equations: At any section, the total compression force should ...
