【摘要】 本义研究了６００ｍ２演播室大空间砖－混凝土组合砌体结构的动力特性，采用振型叠加反应谱法进行 了结构地震反应计算，分析了地震作用下结构的位移特点和内力分布，获得了一些初步结沦，对合理进行该 类结构体系的计算分析工作和抗震设计具有一定的指导意义。文中也指出了该类结构体系有待研究和解决的 一些问题。更多还原

【Abstract】 Dynamic characteristics of large-span brick and concrete mixed structures with an area of 600 square meters are studied in this paper. By using response spectrum method, deformation prop erties and stress distribution of this structure under seismic load are also analyzed. Several conclu sions and suggestions are drawn from the study, which is useful for directing seismic response analy sis and aseismic design for this kind of structures.更多还原
