摘要
在现有研究基础上,经统计分析提出了框架与填充墙各自的性能水平划分及其层间位移角限值.建立了框架填充墙非线性有限元模型.对6、9和12层三个典型框架填充墙结构进行小震、中震和大震下的静力弹塑性分析,得出框架填充墙结构在不同水平地震作用下层间位移角分布.依据抗震性能指标,分析和评估了填充墙框架结构的抗震性能,指出目前规范的不足.根据计算结果,给出了用于评估结构性能的图表.
The performance levels of frame structures and masonry-infilled walls together with corresponding inter-story drift limits were proposed by statistical analysis based on the current research results. A nonlinear finite element model was established for mason-ry-infilled frames. Nonlinear static analysis was performed for 6-,9-,and 12-story masonry-infilled frame structures under frequent, moderate and rare earthquakes and the inter-story drifts were obtained. According to the performance index, the seismic performances of masonry-infilled frames were evaluated and the inadequacy of the Chinese seismic code was pointed out. Based on the calculated results, a table for performance evaluation of masonry infilled frames is given for reference in practical use.
