STRRENGTH AND DUCTILITY OF TRANSVERSELY PROFILED SIMPLY SUPPORTED STEEL PLATE UNDER COMPRESSION

Studied herein is the strength, ductility and energy absorption capacity of simply supported 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. It is concluded that the transversely profied steel plate in the shape of concavity can have superiority in strength, ductility as well as energy absorption capacity.
