The steel beams with folded webs are produced by substituting the folded webs for flat webs, this is a kind of the steel girders with corrugation webs. And such products have superior load-carrying capacity and favorable economic advantages. At present,studies on the behavior of the steel girders under patch loading are scarce at home and abroad. So this paper presents the finite element analysis on folded wed steel girders under patch loading. Observe the failure of the models and the factors that influence the ultimate capacity.
