带耗能支撑再生混凝土框架-剪力墙结构振动台试验研究
SHAKING TABLE TEST STUDY ON RECYCLED CONCRETE FRAME-SHEAR WALL STRUCTURE WITH ENERGY DISSIPATION BRACES
【摘要】 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。
【Abstract】 In order to investigate the seismic performance of a recycled concrete frame-shear wall structure with energy dissipation braces,two frame-shear wall structures were tested on shaking table,including one recycled coarse aggregate concrete model structure,and one recycled coarse aggregate concrete model structure with energy dissipation braces.The dynamic characteristics,dynamic responses,and failure modes of the two model structures in different stages were analyzed and compared through the results from the tests.The tests and analysis results show that the seismic performance of the recycled coarse aggregate concrete frame-shear wall structure with energy dissipation braces is highly improved,and it is able to well satisfy the aseismic capacity according to the current code for seismic design of buildings.
【Key words】 recycled concrete; frame-shear wall; energy dissipation brace; shaking table test; finite element simulation;
