摘　　要：利用框架-抗震墙协同工作计算侧向刚度的方法,计算分析了层1,2侧向刚度比,得出了在层2与底层结构布置完全相同的情况下,当h1/H>0.55时,不能满足侧向刚度比要求的结论。在实际工程设计中,若出现h1/H>0.55情况,应采取相应措施增大底层侧向刚度。The calculation method of lateral stiffness in the condition of frame-shear wall cooperation are used, the lateral stiffness ratio between the first and second storey are calculated and the conclusion that lateral stiffness could not meet practice＇ s need when the first and second storey were provided with the same structure and h 1 / H 〉 0.55 are drawn. When the condition of h 1/H 〉 0.55 comes forth, corresponding measures which fortified ground floor＇s lateral stiffness must be taken.

关 键 词：框架-抗震墙结构 侧向刚度 控制
