摘要

基于ANSYS的有限元数值计算

考查了简支波纹腹板钢梁在火灾作用下的侧向弯扭屈曲。通过与平腹板钢梁的临界温度作比较

研究了波纹腹板钢梁分别在纯弯矩和集中载荷作用下的抗火性能

并分析了栽荷比、初始缺陷等因素对波纹腹板钢梁抗火性能的影响。分析表明

波纹腹板钢梁与平腹板钢梁在火灾作用下有相同的侧向弯扭屈曲性能。

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.
