摘　　要：为了研究地震动各种属性参数和建筑结构反应之间的关联,该文计算了砌体和混凝土结构在地震动作用下的反应或损伤。经过对地震动参数和结构反应相关系数的计算,得到以下结论:有效峰值加速度(EPA)与砌体结构、谱峰值速度(PSV)与低层框架的相关性较好;能够体现地震动持时特性的Arias强度与中层框架和高层砌体存在相关性;地震动峰值加速度(PGA)表现出与所有结构都非常好的相关性;2个能量参数达到了除砌体外与所有结构都非常好的相关性,和砌体结构的反应也存一定的相关性,但不如混凝土结构明显。The structural responses of masonry structures are correlated with earthquake ground motion by a damage index for concrete structures. The correlation coefficient between the structural response and the ground motion parameters shows that the effective peak acceleration （EPA） correlates well with the masonry structure response while peak spectrum velocity （PSV） correlates well with the concrete structures damage index. The peak ground acceleration （PGA） correlated well with the response of all types of the structures. The input energy and hysteretic energy correlated well with response of all structures except masonry structures. The energy parameters also correlated with the masonry structural response hut the correlation is not as strong as with concrete structures.
