带竖缝及金属阻尼器混凝土剪力墙抗震性能研究
|
摘要
为了改善实体剪力墙的延性,提出一种带竖缝及金属阻尼器剪力墙,并设计1/2缩尺的剪力墙试验模型,进行低周反复荷载试验,重点考察试件的承载力、刚度、延性、滞回特性、刚度退化及各阶段的破坏形态。研究结果表明:带竖缝及金属阻尼器混凝土剪力墙与普通混凝土剪力墙相比,承载力和刚度有所降低,竖缝的设置增大了墙体的高宽比,延性得到提高,竖缝内设置金属阻尼器参与耗能,使滞回曲线面积更饱满,从而提高了剪力墙的抗震性能。采用ABAQUS程序对试件进行建模分析,有限元计算结果与试验结果吻合较好,验证了有限元分析模型的正确性。
In order to improve the ductility of shear walls, shear walls with vertical gap and metallic dampers were proposed. 1/2 scale specimens were designed and low cyclic loading test was implemented. The bearing capacity,stiffness,ductility,hysteresis property,rigidity degradation and failure mode at each stage were especially studied. The results showed that the bearing capacity and stiffness of shear walls with vertical gap and metallic dampers decreased when compared with ordinary concrete shear walls. Meanwhile vertical gap could increase the height to width ratio of wall,thus the ductility was enhanced. Installed in vertical seams, metal dampers were involved in energy consumption, which made the hysteresis curve area more full and improved the seismic performance. The finite-element software ABAQUS was then employed for a validated simulation analysis of the models. Comparison of analysis results and test results indicated a good agreement, verifying the correctness of the models.
