洞口大小及形状对剪力墙刚度影响的分析

Analysis on the Influences of Hole's Size and Shape on Shear Wall's Stiffness

随着高层建筑用途逐步从单一性向多样性过渡,剪力墙上的洞口尺寸越来越大,这必将引起剪力墙应力的变化。应用ANSYS程序,对6种不同洞口的剪力墙在顶部水平集中荷载作用下的受力、变形、裂缝进行了分析,并通过对各种剪力墙顶部位移—时间曲线图的分析得出了洞口大小、形状对剪力墙刚度的影响。

Along with the gradual transition of the application of high-rise building from oneness to diversity,the size of the holes on shear wall is bigger and bigger,which would result in the variation of the stress on shear wall.By using ANSYS,this paper makes the analysis on the stress,deformation and crack of the shear walls with six different holes under top horizontal centralized load,and through the analysis on the top displacement-time charts of different shear walls,obtains the influences of hole＇s size and shape on shear wall＇s Stiffness.
