摘要

摘要: 通过调整波纹钢腹板的整体尺寸、波纹板厚度、波折角度、波纹高度和平板宽度等尺寸参数, 制作了16个试验模型, 进行了波纹钢腹板试件的剪切屈曲试验, 记录了不同试件在各级试验荷载作用下的结构变形、应力分布、屈曲荷载与屈曲形态, 对比分析了各个尺寸参数对试件剪切屈曲荷载与屈曲模态的影响。分析结果表明: 根据试件的屈曲形态, 不同尺寸的波纹钢腹板的屈曲破坏主要表现为3种模态; 随整体外形尺寸、波折角度、波纹板厚度的增大及波纹高度的减小, 波纹钢腹板的剪切屈曲荷载随之增大; 整体高宽比对剪切屈曲荷载影响较小。

Abstract: 16 different specimens of corrugated steel web were designed to study the shear buckling property of corrugated steel web, through changing the configuration parameters of corrugated steel web, including overall sizes, thickness and width of corrugated plate, height and angle of setback.Shear buckling test of the specimens were carried out in laboratory.Their structure deformations, stress distributions, shear buckling loads and shear buckling modes were obtained.The influences of above various parameters on the shear buckling loads and buckling modes were analyzed.Analysis result shows that according to the buckling features, the failures of corrugated steel webs with different configuration parameters can be classified into three kinds of main buckling modes.With the increases of overall sizes, angle of setback, thickness of corrugated plate, and the decrease of height of setback, the shear buckling loads of corrugated steel webs rise.The ratio of overall height to width makes little contribution to the buckling loads.
