| 摘 要： | 基于"强水平缝弱竖向缝"的设计理念,对采用软钢阻尼器直接连接腹板墙和翼缘墙的L形装配式剪力墙试件进行低周反复荷载试验。试验结果表明试件的整体工作性能良好,其位移延性系数均大于2.6,具有良好的变形性能;阻尼器平面内工作性能良好,能够实现屈服耗能。设计中应考虑阻尼器的屈服力对单片墙肢轴压比的影响,以满足规范对试件轴压比的要求,同时避免试件在两个加载方向的承载力产生较大差异。

| Abstract: | Based on the design concept of "strong horizontal joints and weak vertical joints",a series of low-cyclic reversed loading tests were carried out on three L-shape fabricated shear wall specimens with web wall and wing wall connected by mild steel dampers.The test results showed that the overall working performance of specimens is good;the displacement ductility coefficient of specimens is greater than 2.6,showing good deformation performance;the damper has good in-plane performance and can achieve yield energy dissipation.The influence of the yield force of dampers on the axial compression ratio of specimens should be considered to avoid a great difference of the bearing capacity of specimens in two loading directions. |
