摘　　要：以钢筋混凝土框架结构为研究对象,选择顶点位移、最大层间位移角、最大基底剪力3种结构性能参数(DM),分析比较不同DM对基于IDA方法结构优化结果的特点和影响,结果表明在结构优化分析时优先使用最大层间位移角作为DM,同时可以选择顶点位移进一步分析,对结构优化进行修正。The reinforced concrete frame structure was taken as research object, three structural damage measures(DM) of vertex displacement, peak inter-storey displacement angle and maximum base shear force were selected, analysis and comparison of different DM on IDA method of structure optimization results and based on the characteristics. It is shown that the peak inter-storey displacement angle is preferentially used as the DM in the structural optimization analysis, and the vertex displacement can be selected for further analysis to correct the structural optimization.
