摘　　要：填充墙对框架结构周期的影响一般采用周期折减系数来考虑,但周期折减系数随砌体材料和填充墙位置变化的规律在业界仍未得到揭示。文章采用数值模拟的方法,分别建立常规混凝土框架模型和混凝土填充墙框架模型,对不同砌体材料下,不同填充墙位置导致的结构自振周期折减系数变化规律展开分析,得到一些鲜为人知的结论,可供结构设计人员在设计中借鉴。The effect of infilled wall on the frame structure period is generally by the periodic reduction coefficient,but the rule of the variation of the periodic coefficient with the masonry material and the position of the infilled wall has not been revealed so far.In this paper,the method of numerical simulation is used to establish the conventional concrete frame model and the concrete infilled wall frame model,and the change law of structural natural vibration period reduction coefficient caused by different infilled wall positions under different masonry materials is analyzed,and some little-known conclusions are obtained,which can be used for reference by structural designers in the design.
