结合国内外对框架结构性能水平的划分标准,将填充墙框架结构的性能水平划分为基本完好、轻微破坏、中等破坏、严重破坏和接近倒塌五个阶段;提出填充墙框架结构各性能水平的失效判别参数和标准,在统计国内外大量试验数据的基础上,提出其不同性能水平对应的层间位移角限值。以等效压杆模型模拟填充墙,采用能力谱方法比较无墙和含墙型框架在地震作用下的响应,并将填充墙框架的实际层间位移与所提性能指标进行比较,结果表明结构在多遇及罕遇地震作用下均满足预定的性能目标。
According to the standard of dividing the performance level of frame structure at home and abroad, the performance level of the filled frame structure is divided into five stages: basic intact, lightly damaged, moderately destroyed, severely damaged and nearly collapsed; Based on the statistics of a large number of test data at home and abroad, the layer displacement angle limits corresponding to different performance levels are proposed. The equivalent wall model is used to simulate wall infill. The ability spectrum method is used to compare the response of wallless and wall-mounted frame under earthquake. The actual interlayer displacement of infilled wall frame is compared with the proposed performance index. The results show that the structure In the event of rare earthquakes and meet the predetermined performance targets.
