阻尼器连接的T形装配式剪力墙抗震性能试验研究

Experimental study on seismic behavior of T-shaped prefabricated shear wall connected with dampers

基于"强水平缝弱竖向缝"的设计理念,对采用阻尼器连接腹板墙及翼墙的T形装配式剪力墙进行了低周反复荷载试验。结果表明,采用阻尼器连接的T形装配式剪力墙整体工作性能良好,其位移延性系数接近或大于3,有良好的变形性能。阻尼器平面内工作性能良好,且能够实现屈服耗能;应考虑阻尼器的屈服力对试件轴压比的影响,避免造成试件在两个方向承载力的较大差异。

Based on the design concept of "strong horizontal joints and weak vertical joints", a low cyclic repeated load test was carried out on the T-shaped prefabricated shear wall with damper connecting web wall and flange wall. The results show that the T-shaped prefabricated shear wall connected with dampers has good performance, its displacement ductility coefficient is no less than 3, and it has good deformation performance. The damper has good performance in plane and can realize yield energy dissipation. The influence of the yield force of dampers on the axial compression ratio of specimens should be considered to avoid the great difference in the bearing capacity of specimens in two directions.
