摘要
本文通过振动台模型试验，研究了上海地区低标准多层砖混结构的抗震性能。利用系统识别方法，得出房屋结构在每一阶段的动力特性参数，分析了影响建筑物抗震能力的主要因素，并对原型结构的抗震能力进行了估算。
This paper presents an investigation on the earthquake resistent behavior of low level standard masonry bulldings subjected to horizontal earthquake action in Shanghai region by model tests on vibrating table- Dynamic characteristic coefficients at every stage of the structure are determined by means of system identification method. Main factors that influence the earthquake-resistunt capacity of a building are analyzed. The aseismic capacity of such prototype buildings is evaluated accordingly,
