A STUDY ON COLLAPSE MODE AND PLASTIC DEFORMATION CAPACITY OF H-SHAPED STEEL BEAMS UNDER SHEAR BENDING

Abstract

In a recent study, it was clear that the beam with large web slenderness has enough plastic deformation capacity for seismic design. But the large deformation behavior and the collapse mechanism of these beams have not been cleared. In this study, the collapse mode and that deciding the maximum load are investigated by experiment study and numerical analysis. As a results, it is clear that the ratio of the shear strength to bending strength of the beam is very important factor for the plastic deformation behavior. And the plastic deformation capacity of the beam is estimated by using the ratio.
