STUDY ON SEISMIC BEHAVIOR OF BRICK MASONRY INFILLED REINFORCED CONCRETE FRAME STRUCTURES

本文介绍了一个1/3比例框架填充墙结构模型模拟地震振动台试验,研究了结构动力特性与反应特征,提出了钢筋混凝土框架砖填充墙结构层间刚度与抗力的简化估计方法和公式,同时进行了多层框架填充墙结构的弹塑性动力反应分析并结合试验模型将计算结果与试验结果进行比较。

In order to have an understanding of the seismic behavior of multistory brick infilled R.C frame structures, a 1/3 scale model of infilled frame building was tested on shaking table by subjecting to a sequence of simulated input motions of progressively increasing magnitude to ultimate failure. Moreover, the dynamic properties and the corresponding changes as the structure degraded were also measured. On the other hand, simplified method and formulas for evaluation of the interstorey lateral stiffnesses and resistances of the infilled frames and seismic response analysis of multi -storey infilled frame structures are suggested. Both the evaluation of stiffnesses and resistances and seismic response analysis were applied to the model test condition and comparisons are given.
