摘要：对钢筋混凝土(RC)框架结构进行增量动力(IDA)分析,以加速度反应谱作为地震动强度指标,层间最大位移角和顶点位移角作为工程需求参数建立IDA曲线簇,并对其进行地震概率需求分析;对RC框架结构进行pushover分析,确定各性能水准的限值,并对其进行易损性分析,得出地震易损性曲线.计算结果表明:选用层间最大位移角作为工程需求参数比顶点位移角更合理;随着结构性能水准由完好过渡到中度损伤状态,结构的超越概率逐渐减小.
Incremental Dynamic Analysis （IDA） was carried out on the RC frame structures. The IDA curves were established by using the acceleration response spectrum as the ground motion Intensity Measures （IMs） with maximum storey drift- ratio and roof drift- ratio as the Engineering Demand Parameters （EDP）. Based on IDA analysis, the seismic demand probability model was also analyzed. Furthermore, the pushover analysis was carried out on the RC frame structure to determine the limiting values under different performance levels, and then the seismic fragility analysis was also completed to achieve the seismic fragility curves. The calculation results indicate that selcting maximum storey drift - ratio as EDP is more reasonable than the roof drift - ratio, and the transcendental probability reduces as performance level transits from good to moderate damage status.
