Abstract

Abstract

The strength of sinusoidal web I-shaped girders under patch loading is not studied well up to now. It wassummarized the previous research work on plane web girders and trapezoidal corrugated web girders, and thenpresented a systemic study on the patch loading behavior of I-shaped girders with sinusoidal corrugated webs. Failuremodes and the influence of initial geometrical imperfection of web were investigated by nonlinear shell elementanalysis. Based upon parametric studies on sinusoidal corrugated web girders, a simplified design formula forestimating the ultimate strength of the girders under patch loading was proposed. In the case of I-shaped girder oftensubjected to combined patch loading and bending moment, an interaction design formula for predicting its limitstrength was proposed accordingly, and validated by FE numerical results.
