RC框架-抗震墙并联结构体系拟静力试验

Quasi-static test of RC frame-seismic wall dual structural system

为研究RC框架-抗震墙并联结构体系中,抗震墙作为"功能集成"与"功能分离"两种形式下结构的抗震性能,进行了2个缩尺比为1∶3的单层两跨的框架-抗震墙试件拟静力试验,分别研究抗震墙主要参与抗侧工作承担小部分重力荷载,与抗震墙既参与抗侧工作又承担重力荷载时试件的裂缝开展与破坏、滞回性能、刚度退化、耗能能力、延性等抗震性能。同时,利用ABAQUS软件对试验试件进行模拟,得到了与试验数据较为吻合的结果。研究表明,当抗震墙的承重功能与抗侧功能基本分离时,结构具有更好的延性、耗能能力与损伤发展过程。

In order to study the seismic performance of two different forms of structures,i. e. "functional integration" and "functional separation" in the Reinforce Concrete(RC)frame-seismic wall dual structure system,quasi-static tests of two 1/3 scale frame-seismic wall specimens with two single-story and twobay were carried out. The damage development, hysteretic behavior, stiffness degradation, energy dissipation capacity,ductility and other seismic behaviors of the seismic wall were investigated as the wall mainly bears the lateral resistance but bears a small part of the vertical load,and as the wall bears both the lateral resistance and the vertical load. The performance of the specimens was also studied by ABAQUS finite element software simulation,and the results are consistent with the test results. The results of this study show that the structure has better ductility,energy dissipation capacity and damage development process when the load-bearing function and the anti-lateral function of the seismic wall are separated.
