摘要: 基于5榀型钢高性能混凝土梁低周反复加载试验,对梁的破坏形态以及不同参数下梁的荷载-位移滞回曲线、骨架曲线、延性和耗能能力等方面的规律和特点进行较为系统的研究。分析不同设计参数对梁抗震性能的影响。结果表明:在低周反复荷载作用下,经过合理设计的型钢高性能混凝土框架梁一般发生弯曲型破坏,且具有良好的延性和抗震耗能能力。

Abstract: Based on the test of 5 steel reinforced high performance concrete(SRHSHPC) beam specimens under low cycle reversed loading,the failure model,hysteretic curves,skeleton curves,ductility and energy dissipation capacity of frame beams with different design parameters were studied.The seismic performance of the beams was analyzed.The results indicate that the reasonably designed SRHSHPC beams subjected to low cycle reversed loading produce flexure failure normally,and possess of good ductility and energy dissipation capacity.
