摘要

研究开发一种带缝保温耗能钢筋混凝土剪力墙结构,这种新型多功能剪力墙既保持了普通钢筋混凝土剪力墙的优点,又克服了普通剪力墙自重大、延性差等缺点。设计制作了6组带缝保温耗能剪力墙试件,通过水平低周反复荷载试验,研究了其受力变形特征、破坏形态、耗能机理等力学性能,分析了轴压比、连接键等因素对剪力墙抗震性能的影响。研究结果表明,竖缝及连接键的设置对剪力墙结构的抗震性能影响较大,合理设置连接键可以在承载力降低较少的情况下,较大程度地提高剪力墙的抗震性能和变形能力;新型多功能剪力墙表现为弯剪型变形特征,由于破坏机理的改变,使其抗震性能、耗能能力得到提高,体现了多道设防的抗震设计思想。
A new type of slitty shear wall,named multi-functional shear wall,is presented in this paper,which consists of heat-perservation layers and energy-dissipation components.Six speciments were designed and fabricated to investigats its seismic behaviors.Under cyclic reversed loading,the internal force,deformation,energy dissipated and failure pattern are examined.It is shown that the reasonably designed vertical slit and connecter in the wall can effectively improve the wall's seismic behavior.The new type multi-function wall fails in bend-shear mode with improved deformation capacity and energy-dissipation characteristics.Multi seismic resistances can also be observed in this new type multi-functional shear wall.
