通过二榀带有X形支撑的框撑钢筋混凝土复合剪力墙和一榀带有边框的钢筋混凝土剪力墙在低周 反复荷载作用下的对比试验,着重研究了复合剪力墙的抗震性能、延性、耗能性能和破坏机制,并给出了这种 复合剪力墙恢复力计算模型。试验表明:钢筋混凝土复合剪力墙刚度大,能吸收地震能,延性好,能大量消耗 地震能,它与框架配合能够形成刚柔相济,变形协调的新型减震耗能结构体系。
Through the comparison tests of the framed reinforced concrete composite shear walls with X-shaped bracings and the reinforced concrete shear walls with a frame at the low cyclic loading, the seismic behavior of composite shear walls , Ductility, energy dissipation performance and failure mechanism, and gives the calculation model of the resilience of this composite shear wall. The tests show that the RC shear wall is large in stiffness and absorbs seismic energy with good ductility. It can consume a large amount of seismic energy. It can cooperate with the frame to form a new type of shock-absorbing and energy-dissipative structure system that is rigid-flexible and deformable.
