摘　　要：提出了一种新型的抗震结构体系———摩擦阻尼式剪力墙 ,通过三片剪力墙试验 ,研究了摩擦阻尼式剪力墙在反复荷载作用下的破坏机理和破坏形态 ,比较了整片墙、开缝墙、开缝加阻尼器三种墙的延性和耗能差异。结果表明 ,摩擦阻尼式剪力墙在延性、耗能及动力反应上都明显要好于其他形式的剪力墙 ,这种力墙体系作为第二道防线 ,使结构在地震中损害减小。A new type of aseismic structural system——frict ion damping shear wall is proposed. It is studied that the failure mechanism and mode of the friction damping shear wall under repeated loadings through tests o f three shear walls. The ductility and energy disspation are compared among a mo nolithic shear wall, a slit shear wall and a shear wall with slit and damper. Th e results show that the ductility, energy disspation and dynamic response of the friction damping shear wall are much better than those of other types of shear walls, by which the damage to a structure under earthquake can be decreased.
