Plastic collapse load of continuous composite plate girders

Abstract

The object of this study is to pursue the applicability of the Autostress Design method for continuous composite girders. The ultimate bending strength and the moment-rotation characteristics are investigated using the experimental data of noncompact beams and plate girders. An idealized moment-curvature curve for the negative moment section is proposed. Finally, a simple plastic analysis of two-span continuous composite girders is presented and discussed.
