摘要:
通过8个1/2比例的核心型钢混凝土(CSRC)框架柱的抗震性能试验,研究轴压比和核心型钢配钢率对CSRC柱滞回特性的影响,以及CSRC柱在不同抗震性态水平的变形指标和抗震性能指标.结果表明,CS-RC柱具有良好的变形能力和滞回耗能能力,配置核心型钢可有效提高重载RC柱的抗震性能.对于运行和基本运行性能水平,可采用纵筋、核心型钢应变和试件荷载水平作判定参数; 对于可修性态水平,可采用残余位移角作判定参数; 而对于避免倒塌性态水平,可采用试件承载能力的衰减和滞回环的稳定状态作判定参数.
Abstract:
Eight half scaled core steel reinforced concrete(CSRC) columns are tested to study the influence of axial compression ratio and core steel ratio to the hysteretic behavior and the seismic performance parameters under different performance levels of CSRC columns.It is indicated that CSRC columns own good deformation capacity and hysteretic energy dissipated capacity.The seismic behavior of RC columns with high axial load can be effectively improved by using core steel.For the fully operational or operational performance levels,the strain level of longitudinal bars and core steel,the load level of specimens can be taken as the performance parameters.For the repairable performance levels,the residential storey drift can be taken as the performance parameter.For the collapse prevention performance level,the degradation of strength and the stability of hysteretic hoops can be taken as the performance parameter.
