摘要
为了提高矩形高层建筑中开菱形孔钢板墙的稳定性,提出一种基于力学模型分析的开菱形孔分析模型,推导了钢板墙中菱形孔带的受压力和稳定性分析的理论公式,并以开菱形孔尺寸为主要参数,对开菱形孔钢板墙进行了受压稳定性试验。试验结果表明:当菱形孔的宽度适中时,开菱形孔钢板墙的承载力和稳定性较高,能够满足矩形高层建筑中对于钢板墙的稳定性的要求;当菱形孔的参数h/a、h/b、h/H、h/t(其中h为菱形孔的高度,a为菱形孔带中间截面宽度,b为菱形的孔宽度,H为钢板的高度,t为钢板的厚度)分别减少时,钢板墙的承载力有着不同程度的增大,钢板墙的稳定性也随之增加。
In order to improve diamond holes in rectangular high-rise building steel plate wall stability,put forward a model based on mechanics analysis of open hole analysis model of diamond, the diamond hole of steel plate wall was deduced with the formula of the stress and stability analysis theory, and the size of the diamond hole as the main parameter, split the diamond hole plate wall pressure stability tests have been carried out. Experimental results show that when the width of the diamond hole is moderate,open the diamond hole steel plate higher bearing capacity and stability of the wall, can satisfy the rectangle to the requirement of the stability of the steel plate wall in high- rise buildings; When the parameters of the diamond hole h/a , h/b , h/H , h/t (in which h is the height of the diamond hole, for the diamond hole with a middle section width, b for the diamond hole width, h is the height of the steel plate, t is the thickness of the steel plate), respectively, to reduce, the bearing capacity of the steel wall with different degree of increase, the stability of the steel plate wall also will increase.
