ACCURACY OF THE FIBERED PLASTIC HINGE MODEL FOR ELASTOPLASTIC ANALYSIS OF DOUBLY ASYMMETRIC SECTION MEMBER

Abstract

Elastoplastic behaviors of unequal-legged angle, which is a typical doubly asymmetric section member, under some different boundary and loading conditions are investigated by experiments and numerical analyses. The numerical analyses are done by using a new straight beam element proposed by the first author. Comparisons of the numerical results with the experimental ones about the load-displacement relations and load-strain relations for four cases show that the beam element has a sufficient accuracy for the elastoplastic large deformation analysis of unequal-legged angles.
