Research on Structural Seismic Control and Energy Dissipation with Experiments and Application

为了改善高层剪力墙结构的抗震性能，根据结构控制的原理提出了一种新型剪力墙—沿竖向消能的带竖缝剪力墙。首先，进行了竖缝处消能装置的剪切—摩擦试验，研究了这种消能装置的受力机理和消能机理，给出了荷载—位移骨架曲线的理论计算方法。其次，进行了带有此消能装置的一层带竖缝剪力墙和普通实体墙的低周反复荷载试验，对比研究了这两类剪力墙的破坏机理和滞回特性，试验表明这种新型消能剪力墙具有良好的抗震性能。接着，讨论了这种剪力墙的消能计算方法。最后，介绍了消能剪力墙的一个工程应用实例。

In order to improve the seismic behavior of shear wall structures,a new type of shear walls,which dissipates energy along vertical direction,is proposed based on the principle of structural control.At first,the shear friction tests of the energy dissipating devices in the vertical slit were carried out.The load transfer mechanism is studied,then the method for calculating the force displacement skeleton curve is presented.Next,one story vertically slitted shear wall models with the energy dissipating devices and solid shear wall models were tested under cyclic loads.The failure mode and hysteretic characteristic are compared,which proves good seismic performance of this new type of shear walls.The method for calculating the dissipated energy is discussed too.At last,an example for engineering application of this new type of shear walls is introduced.
