开洞填充墙钢框架抗震性能分析
|
摘要
为了探究钢框架填充墙中洞口位置及尺寸变化对钢框架体系极限承载力和抗震性能的影响,使用ANSYS有限元软件建立6个足尺模型,对不同开洞位置及开洞尺寸的模型的极限承载力、滞回曲线以及耗能能力进行系统分析。结果表明:当开洞面积相同时,虽然洞口位置的变化对承载力有一定影响,但填充墙体与钢框架接触面积对其的影响更为突出;当开洞位置一定时,填充墙钢框架的极限承载力随开洞面积的增大显著降低,但其延性性能和耗能能力却有不同程度的提高。
In order to research the influence of variation of hole's location and size on the ultimate bearing capacity and seismic behavior of opening hole infilled wall with steel frame,through ANSYS finite element software,this paper analyzes the ultimate bearing capacity,hysteresis curve and energy consumption capacity of six models between different position and size of hole.The result shows when opening hole area is the same,the change of hole position has certain effect on the bearing capacity,but more important is the influence of contact area between the infilled wall and the steel frame.When the position of hole is certain,the ultimate bearing capacity of infilled wall with steel frame decreases with the increase of the area of hole,but the ductility performance and energy dissipation capacity are improved to some degree.
