The Parametric Analysis and Simulation for Lateral-torsional Buckling of Steel Girders with Corrugated Webs in Fire Conditions
摘要
Abstract
This paper investigates lateral torsion-flexure buckling resistance of steel girders with corrugated webs in fire conditions. Compared to steel girders with planar webs, critical temperature of corrugated webs beams subjected to uniform moments and concentrated loads were studied, respectively. The effect of load ratio and initial defects on critical temperature of steel girders with corrugated webs was analyzed. The results show that lateral torsion-flexure buckling resistance of steel girders with corrugated web in fire is the same as that of planar webs girders.关键词
