【摘要】 本文运用有限元分析软件ETABS对框架-剪力墙结构进行弹性时程对比分析研究,通过改变一层的嵌固面积百分比,做了8个对比模型。《高规》规定了框架-剪力墙结构底部嵌固层与相邻上层的侧向刚度比不宜小于1.5,研究得出此项规定不适用于不等高嵌固时对嵌固端的选取。需要对比模型的其他各项性能指标综合考虑。更多还原

【Abstract】 In this paper,the software ETABS for finite element analysis was used to make elastic dynamic analysis of frame-shear wall structure.Eight contrast models were made for changing the percentage of fixed area on the first floor.JGJ3-2010 stipulated that the lateral stiffness ratio of bottom fixed floor to adjacent upper floor of frame-shear wall structure should not be less than 1.5.But the study showed that this rule can not apply to choosing the partial fixing of structure with varied solid ends,which needed to contrast various performance indexes of the models.更多还原
