STRRENGTH AND DUCTILITY OF TRANSVERSELY PROFILED COMPRESSION FLANGE OF STEEL I SECTION

Abstract

Studied herein is the strength, ductility and energy absorption capacity of steel plate profiled transversely under uniform compression. In order to assess the effect of the taper ratio of steel plate thickness on the structural performance, the elasto-plastic finite displacement analysis is carried out, varying the taper ratio as well as the plate slenderness parameter. The analysis is also extended to assess the bending performance of I-shaped steel member with tapered flange and web. It is concluded that the transversely profiled steel plate in the shape of convexity can have superiority in strength, ductility as well as energy absorption capacity.
