【摘要】 预应力横缝摩擦剪力墙是一种新的有效的抗震结构型式。 本文以试验结果为依据,对设有预应力横缝摩擦剪力墙的层间结构,提出采用多段折线型恢复力模型,并给出了有关参数的计算公式。在此基础上建立了这种新型结构地震反应的计算方法。 文中附有算例。计算结果表明,摩擦缝的滑动能明显地消减地震荷载。借助框架柱的变形能力可大大地耗散地震能量。更多还原

【Abstract】 The reinforced concrete multi-storeyed shear wall structure with vertically prestressed slidable horizontal friction joints is a new type of earthquake-resistant structure. Grounded upon the experimental findings, the interstory wall element with such joints is assumed to take its restoring force characteristics curve as shown in Fig.l in the paper. Formulae for determining the parameters in elastic and elasto-plastic stages are derived and presented. They serve as a base in establishing an approach for seismic response analysis of the structure.Numerical examples are given. The results show that the slide of joint can considerably reduce the earthquake load and that the seismic energy induced will greatly be dissipated by dint of the fine deformability of the reinforced concrete frame columns.更多还原
