备注

为研究底部腋角配置斜向钢筋装配叠合管廊抗震性能,通过一个管廊进行拟静力试验,测试其在模拟地震力作用下的滞回性能、刚度退化、耗能能力及延性性能等指标,得出结构的承载能力、屈服位移和极限位移等.研究结果表明,底部腋角配置斜向钢筋装配叠合管廊具有较好的滞回性能、变形与耗能能力,且水平卸载后的残余变形较小,有利于结构震后修复.

In order to study the seismic performance of the assembled composite pipe gallery with inclined reinforcement at the bottom axillary angle,a quasi-static test was carried out on a pipe gallery to test its hysteretic performance,stiffness degradation,energy dissipation capacity and ductility performance under the action of simulated seismic force,and the bearing capacity,yield displacement and ultimate displacement of the structure were obtained.The results show that the composite pipe gallery with inclined reinforcement at the bottom axillary angle has better hysteretic performance,deformation and energy dissipation capacity,and the residual deformation after horizontal unloading is small,which is beneficial to the post-earthquake repair of the structure.
