［摘要］某高層框架-剪力墻結(jié)構(gòu)為豎向不規(guī)則結(jié)構(gòu)，結(jié)構(gòu)總高度67m，地上13層。設(shè)計(jì)時(shí)提出了兩個(gè)方案，并對(duì)兩個(gè)方案的整體抗震性能進(jìn)行了分析和對(duì)比。方案一為減小11~13層剪力墻、框架柱截面，減少剪力墻數(shù)量，10層側(cè)向剛度比滿足規(guī)范要求；方案二為保持11~13層框架柱截面不變，減小剪力墻截面和數(shù)量，10層側(cè)向剛度比不滿足規(guī)范要求。采用SATWE和SAUSAGE軟件對(duì)這兩個(gè)方案分別進(jìn)行了小震彈性分析和大震動(dòng)力彈塑性分析。結(jié)果表明，方案一的樓層受剪承載力和層間位移角在10層存在突變，11~13層為薄弱樓層，鞭梢效應(yīng)明顯；方案二的樓層受剪承載力和層間位移角在10層無突變，無薄弱樓層，其整體抗震性能優(yōu)于方案一；工程設(shè)計(jì)應(yīng)采用方案二，抗震設(shè)計(jì)不應(yīng)片面地消除不規(guī)則項(xiàng)，而應(yīng)使結(jié)構(gòu)的整體抗震性能更優(yōu)。

Abstract: A high-rise frame-shear wall structure is a vertical irregular building, with a total structure height of 67m, the total number of floors above ground is 13. Two schemes were proposed in the design, and the overall seismic performance of the two schemes was analyzed and compared. Scheme 1 is to reduce the section of the 11~13 storeys shear walls and frame columns, and reduce the number of shear walls. The lateral stiffness ratio of the 10 storey meets the specification requirements. Scheme 2 is to keep the 11~13 storeys frame column section unchanged and reduce cross-section and number of shear walls. The 10 storey lateral stiffness ratio does not meet the specification requirements. SATWE and SAUSAGE softwares were used to carry out small earthquake elastic analysis and large shock elastic-plastic analysis for these two schemes respectively.The results show that there is a sudden change in the storey shear capacity and the storey drift angle of Scheme 1 on the 10 storey, and the 11~13 storeys are weak floors, and the whiplash effect is obvious. The storey shear capacity and the storey drift angle of Scheme 2 on the 10 storey have no abrupt changes and no weak floors, its overall seismic performance is better than Scheme 1. The engineering design should adopt Scheme 2, and the seismic design should not eliminate irregularities one-sidedly, but should make the overall seismic performance of the structure better. 

Keywords:vertical irregularity； stiffness break； dynamic elastic-plastic analysis； seismic performance
