摘要

为提升自复位预制双肢剪力墙的耗能能力，本文针对预制双肢剪力墙提出了一种拼缝阻尼器，该阻尼器可适应接缝附近的大变形，帮助结构同时实现自复位和耗能的性能。通过拟静力试验，获得了该阻尼器的滞回曲线，验证了所提阻尼器具备良好的耗能性能；使用Opensees把阻尼器放入预制双肢剪力墙中进行数值分析，发现所提阻尼器在不降低结构原本自复位性能的同时，大大提升了结构的耗能能力。同时，耗能主要由拼缝阻尼器承担，结构自身的耗能和损伤较小，有利于实现结构在震后的快速修复。

Abstract

To improve the energy consumption of self-centering prefabricated coupled shear wall, an open-close gap damper (OCGD) was proposed, which can adapt to large deformations near the joints and help the structure achieve both good self-centering and energy-dissipation ability. Static tests were used to obtain the hysteresis curve of the damper, which verified good energy dissipation abilities of the proposed damper. Through simulation by Opensees, it was found that the proposed damper greatly improved the energy consumption of the structure without reducing its original self-centering ability. In addition, the energy was mainly dissipated by the open-close gap dampers. The energy consumption and damage of the structure itself were small, which creates the possibility for quick repair after the earthquake.
