低屈服点钢板剪力墙抗侧刚度及抗剪承载力研究
|
摘要
在水平荷载作用下,低屈服点钢板剪力墙的边缘框架与内填钢板协同工作,共同参与抵抗水平力。边缘框架类似于纯抗弯框架,内填钢板会对边缘框架产生附加作用。考虑内填钢板对边缘框架的附加作用,对边缘框架和内填低屈服点钢板剪力墙钢板的抗侧性能分别进行理论分析,得到低屈服点钢板剪力墙的抗剪承载力及各阶段的抗侧刚度。利用ANSYS分析不同宽厚比低屈服点钢板剪力墙在单调水平荷载作用下的抗侧性能,并与理论分析结果对比,证明理论推导公式具有较好的准确性。
Under the horizontal load, the infill plate and frame of low yield point steel plate shear wall can work together to jointly participate in the resistance to lateral force. The frame is similar to moment-resisting frame, while the infill plate will generate additional effect in the frame. Considering the effect in the frame, the lateral performance of the frame and infill plate is analyzed theoretically to obtain the ultimate shear capacity and the lateral stiffness. Analyses are performed to study the lateral resistant performance of low yield point steel plate wall with different ratio of width to thickness under monotonic horizontal load by ANSYS. Compared with the theoretical analysis, the theoretical formulas are proved with good accuracy.
