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。
Sixteen test models were made by adjusting the overall dimensions of the corrugated steel web, the corrugated board thickness, the corrugation angle, the corrugation height and the width of the flat plate, and the buckling test of the corrugated steel web was made. The differences The structural deformation, stress distribution, buckling load and buckling mode of specimen at all levels under test load were analyzed. The influence of each dimension parameter on the shear buckling load and buckling mode was analyzed. The results show that the buckling damage of corrugated steel webs with different sizes is mainly manifested as three kinds of modes according to the buckling morphology of the specimens. With the increase of overall dimensions, waviness angle, corrugated board thickness and corrugation height, The shear buckling load of corrugated steel web increases with the increase of shear buckling load.
