中文摘要：
进行6个1／2比例的型钢混凝土框架柱（SRC）的低周反复加载试验，主要研究轴压力系数和体积配箍率对型钢混凝土柱滞回特性的影响和SRC柱在不同抗震性态水平的变形指标．通过试验结果分析了SRC柱试件的破坏形态、变形能力、滞回特性等抗震性能指标．基于不同性能水平下的变形和相关参数试验结果，提出了以裂缝宽度和纵向钢筋应力水平、残余变形、极限转角分别作为正常使用、可修和避免倒塌等性能水平的评定参数，并建议了相应性能水平的限值．该研究成果可供型钢混凝土结构基于性能的抗震设计研究和工程实践参考．
英文摘要：
Six half scale steel-reinforced concrete （SRC） columns were put on test under cyclic loading. The effects of the axial compression ratio and stirrup ratio on the hysteretic characteristics of SRC columns and the seismic performance parameters for performance based seismic design of SRC columns were investigated. The failure mechanism, ductility, and hysteretic behavior were analyzed. According to the damage characteristics and measurement results, a series of performance parameters and corresponding limit value that can be used to appraise the performance level of SRC columns under earthquake was proposed. It is indicated that the crack width and stress level of longitudinal bar, residual drift and ultimate drift index can be adopted as the key parameter to appraise the seismic performance of functional, repairable and collapse avoidable capacities respectively.
