Experimental Study on Flexural Behavior of Box-Shape Profiled Steel Sheet Integrating with System Effect

  • 摘要:

    为研究外层钢板及衬檩对盒状压型钢板受弯性能的影响,考虑风压和风吸两种荷载,对8个双层压型钢板的组合试件和2个盒状压型钢板的标准试件进行了受弯加载试验,分析了外层钢板刚度、衬檩高度对盒状压型钢板的受弯承载力、受弯刚度的影响. 试验结果表明:1) 当衬檩高度为100 mm时,外层钢板为Ⅰ型和Ⅱ型的组合试件相对于标准试件,在风压荷载下的受弯承载力分别提高27.6%和111.3%,受弯刚度提高17.3%和56.7%;在风吸荷载下的受弯承载力分别提高32.1%和77.6%,受弯刚度提高29.4%和48.1%. 2) 当外层钢板为Ⅱ型时,衬檩高度为200 mm和100 mm的组合试件相对于标准试件,在风压荷载下的受弯承载力分别提高66.9%和111.3%,受弯刚度提高39.9%和56.7%;在风吸荷载下的受弯承载力分别提高59.1%和77.6%,受弯刚度提高33.5%和48.1%. 3) 考虑外层钢板及衬檩的整体效应可提高盒状压型钢板的受弯承载力和受弯刚度,且外层钢板的刚度越大,衬檩高度越低,提高幅度越明显. 4) 提出的考虑整体效应的盒状压型钢板受弯计算式其计算结果与试验结果吻合良好.
