采用框架与填充墙协同工作并联模型,对两个容重级别轻集料混凝土砌块填充墙的框架结构进行动力分析。分析显示两种砌块对结构的自振周期影响不同;同一种砌块填充墙的填充数量和填充位置对结构的自振周期影响也存在差异。在工程中,要根据填充墙的实际状况合理的进行周期折减,以使结构在地震作用下计算更切合实际。
The frame structure of the lightweight aggregate concrete block infill wall with two bulkheads is analyzed by using the parallel working model of frame and infill wall. The analysis shows that the two kinds of masonry have different influences on the natural period of the structure. The filling amount and filling position of the same type of masonry filled wall also have different effects on the natural period of the structure. In the project, according to the actual situation of the infill wall reasonable period reduction, so that the structure under the action of the earthquake more realistic.
