为了研究带耗能支撑再生混凝土框架-剪力墙结构的抗震能力,进行2个框架-剪力墙结构模型的模拟地震振动台试验研究,其中1个为再生粗骨料混凝土普通框架-剪力墙结构,1个为再生粗骨料混凝土带耗能支撑框架-剪力墙结构。对比分析了2个模型不同受力阶段的动力特性、地震反应及破坏形态,结果表明:耗能支撑能明显提高再生混凝土框架-剪力墙结构的抗震能力,使其较好地满足现行抗震设计规范要求。
In order to study the seismic capacity of a RC frame-shear wall structure with energy dissipation, two frame-shear wall structure models are simulated and simulated by shaking table test. One of them is a common frame of recycled coarse aggregate concrete-shear Wall structure, one for the recycled coarse aggregate concrete with energy-saving support frame - shear wall structure. The dynamic characteristics, seismic responses and failure modes of the two models under different stress stages are compared and analyzed. The results show that the energy dissipation supports can significantly improve the seismic capacity of the RC frame-shear wall structure and make it meet the requirements of the current seismic design requirements.
