Influence of Axial Forces on Plastic Moment

Abstract

In Chapter 11, the analysis is based on the principle of pure bending. Although this assumption is valid for continuous beams, other secondary effects have to be included in the analysis and design of frames. Secondary effects are attributed to a number of factors such as axial forces, shear forces, buckling (local, lateral, column), repeated loading (fatigue), and brittle fracture. In this text, only the effect of axial loads and shear forces will be included in considering a plastic failure in members of a structural system. The analysis of plastic failure is based on the theory of small deformations.
