摘要
本文对不同轴压比和配箍率下承受低周反复荷载作用的９根不同配筋构造的框架柱铰的延性、滞回特性和耗能能力等抗震性能进行了试验研究。结果表明，和普通方箍柱相比，井字式复合箍筋柱具有良好的抗震性能；柱铰内埋工字钢可以显著地改善框架柱的抗震性能。
In this paper,the seismic behavior of plastic hinges,namely the ductility,the capacity of energy dissipation, and the hysteretic response,in frame columns subjected to axial force and low cyclic loading have been studied.9 column specimens with different constructional reinforcement,different stirrup ratios and different compression ratios have been tested.Experimental results show that in comparison with columns reinforced with ordinary square stirrups,the columns with compound tie hoops have better performance under earthquake actions,while those encased with I-bars show good seismic behavior for columns with high axial compression ratio
