［提要］  利用框架-抗震墻協(xié)同工作計算側(cè)向剛度的方法，計算分析了層1，2側(cè)向剛度比，得出了在層2與底層結(jié)構(gòu)布置完全相同的情況下，當(dāng)h1/H>0.55時，不能滿足側(cè)向剛度比要求的結(jié)論。在實際工程設(shè)計中，若出現(xiàn)h1/H>0.55情況，應(yīng)采取相應(yīng)措施增大底層側(cè)向剛度。

Lateral Stiffness Control of the First to Second Story in Masonry Building with Two Stories Frame and Shear Wall at the Bottom/Li Jiuhong(Zhongzhou University，Zhengzhou 450005,China)

Abstract: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 h1/H>0.55 are drawn.When the condition of h1/H>0.55 comes forth,corresponding measures which fortified ground floor"s lateral stiffness must be taken.
