[摘要] 采用ABAQUS對(duì)23個(gè)鋼管混凝土框架一鋼筋混凝土核心筒結(jié)構(gòu)分析模型進(jìn)行了大震彈塑性時(shí)程分析，分析模型變量為樓層總高度、地震波及地震波峰值加速度。通過(guò)對(duì)23個(gè)算例中25個(gè)典型樓層的位移與能量分析，提出了基于除連梁外結(jié)構(gòu)的塑性耗能及樓層有害位移角的樓層損傷因子的計(jì)算公式。計(jì)算得到的樓層損傷因子與樓層的損傷現(xiàn)象基本吻合。該計(jì)算公式可用于定量評(píng)估樓層的損傷程度。

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.
Keywords: floor damage degree; assessment method; elastic-plastic time-history analysis; energy
