[摘要] 采用ABAQUS对23个钢管混凝土框架一钢筋混凝土核心筒结构分析模型进行了大震弹塑性时程分析，分析模型变量为楼层总高度、地震波及地震波峰值加速度。通过对23个算例中25个典型楼层的位移与能量分析，提出了基于除连梁外结构的塑性耗能及楼层有害位移角的楼层损伤因子的计算公式。计算得到的楼层损伤因子与楼层的损伤现象基本吻合。该计算公式可用于定量评估楼层的损伤程度。

Abstract: Elastic-plastic time history analysis under large earthquake of 23 CFST frame-reinforced concrete core wall structure models have been done by ABAQUS. Variable parameters are structural height, earthquake wave and peak acceleration of wave. Formula of floor damage factor is proposed by analysis of displacement and energy of 25 typicalfloors. The formula is based on harmful displacement angle and plastic energy of structure exclude coupling beams. The calculated floor damage factors agree with the damage phenomena. The proposed formula can be used to evaluate the floor damage degree quantitatively.
