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 the stability of diamond-shaped perforated steel wall in rectangular high-rise building, a model of open hole analysis based on mechanical model analysis is proposed, and the theoretical formula of stress and stability analysis of diamond shaped hole in steel wall is derived. Diameter of diamond-shaped hole as the main parameter, open the hole wall of diamond-shaped hole under pressure stability test. The test results show that the bearing capacity and stability of the diamond-shaped perforated steel plate wall are high when the width of the diamond-shaped hole is moderate, which can meet the requirements for the stability of the steel plate wall in the high-rise rectangular building. When the parameters of rhombic hole h / a, (where h is the height of the diamond hole, a is the width of the middle section of the diamond hole, b is the width of the diamond hole, H is the height of the steel plate and t is the thickness of the steel plate) When the bearing capacity of the steel wall has increased in varying degrees, the stability of the steel wall also increases.
