摘要

以两层钢筋混凝土框架为原型,按1∶2的缩尺比例设计了2榀钢筋混凝土框架。对其中1榀进行了低周反复试验,对另1榀采取屈曲约束支撑加固后进行低周反复试验。试验主要研究了原型框架和屈曲约束支撑框架的受力性能、破坏形态、滞回特性以及位移延性等,并采用Seismostruct 5.03程序对试验过程进行数值模拟分析。结果表明,屈曲约束支撑混凝土框架的抗震性能有了较好的改善。
Based on a two-layer RC frame building,two RC frames are designed with the scale 1∶2.One RC frame is tested by low-reversed cyclic loading,another RC frame is tested by low-reversed cyclic loading with buckling-restrained braces.Based on the tests,the force performance,failure mode,hysteretic behavior,and displacement ductility of two RC frames are analyzed.The tests are examined by numerical simulation anlysis of the seismostruct 5.03.The results show that the seismic behavior of RC frame with buckling-restrained braces is improved significantly.
