空心剪力墙结构抗震性能试验研究
|
摘要
通过对十层空心剪力墙结构模型和六层带竖缝空心剪力墙结构模型进行不同峰值加速度的拟动力试验和低周反复水平荷载作用下的拟静力试验,研究这两种结构在地震作用下的动力特性的改变、结构的破坏形态、变形特征以及延性等。试验结果表明,空心剪力墙结构的承载能力较高;在弹性阶段,空心剪力墙结构的刚度较大,变形较小;在弹塑性阶段,结构的变形增加较多,带竖缝空心剪力墙的墙肢被分割成多个小墙肢,结构利用其优良的延性来消耗地震能量。空心剪力墙结构是一种性能良好的墙体,可用于地震区的多层和小高层建筑,而带竖缝空心剪力墙结构的抗震性能更优。
Based on the pseudo-dynamic and pseudo-static under low-cycle test of 10-storey model building without seams and 6-storey model building with seams,the change of dynamic characteristics,the failure mechanism,the deformation feature and ductility of two type structure are discussed.The result of experimental study proved that,the capacity of hollow shear wall is well;In elastic stage,the hollow shear wall are high stiffness and little deformation;In elastic-plastic stage,the deformation is raise,and the slit hollow shear wall are divided into several little walls,the property of energy dissipation of hollow shear wall structure is good.The seismic behavior of the slit and integral hollow shear walls are used in the multi-story and low high rise building.
