摘要
为了进一步研究开圆洞钢板剪力墙的抗震性能,以墙板厚度、开洞率和开洞半径等为研究参数,利用有限元软件ABAQUS设计3组模型试件进行滞回模拟。研究表明:当钢板剪力墙厚度在6~8 mm时,墙板耗能能力随着厚度的增加而快速提高,当墙板厚度在8~10 mm时,墙板耗能能力增加速度放慢;开洞率越大导致墙板刚度削弱越严重,墙板承载力越低,而当开洞率保持在10%左右时,墙板整体耗能性能较好;在相同开洞率情况下,开洞半径为80 mm的剪力墙板耗能性能在对比模型中表现最佳,墙板承载力在加载后期仍然有上升趋势且墙板面外屈曲变形较小。
In order to further study the seismic performance of perforated steel plate shear wall,three groups of model specimens were analyzed using finite element software ABAQUS for hysteretic simulation with the plate thickness,opening rate and opening radius as the research parameters.The research shows that when the thickness of the steel plate shear wall is between 6 mm and 8 mm,the energy dissipation capacity of the steel plate shear wall increases rapidly with the increased thickness.When the thickness is between 8 mm and 10 mm,the energy dissipation capacity increases slowly;the larger the opening rate,the more serious the stiffness weakening and the lower the bearing capacity of the steel plate shear wall.When the opening rate is about 10%,the overall energy dissipation performance of the steel plate shear wall is excellent.With the same opening rate,the shear wall panel with opening radius of 80 mm has the best energy dissipation performance in the comparison model,the bearing capacity of the shear wall still tends to increase in the later stage of loading and the out-of plane buckling deformation of the wall panel is smaller.
