［摘要］為評價成都某框架-剪力墻超限項(xiàng)目的大震安全性，采用SAUSAGE和ABAQUS進(jìn)行彈塑性時程分析。通過SAUSAGE計(jì)算，結(jié)構(gòu)頂部X向和Y向最大位移分別為0-248m和0-183m， X向和Y向最大層間位移角分別為1/271和1/237，X向與Y向最大基底剪力與小震CQC法基底剪力的比值分別為3-6和3-9，構(gòu)件損傷情況均滿足大震下性能目標(biāo)D的相關(guān)要求。同時，通過ABAQUS與SAUSAGE分析結(jié)果對比，總質(zhì)量、特征周期、位移曲線、層間位移角曲線、基底剪力時程曲線以及構(gòu)件損傷基本相同，驗(yàn)證了SAUSAGE分析結(jié)果的準(zhǔn)確性。此外，通過ABAQUS計(jì)算，剪力墻部分在6s時開始進(jìn)行耗能，框架部分在13s時開始進(jìn)行耗能，說明框剪結(jié)構(gòu)中剪力墻起到了第一道抗震防線作用，框架部分起到了第二道抗震防線作用。

Abstract:In order to evaluate the safety of  a frame-shear wall over-limit project in Chengdu under large earthquakes, SAUSAGE and ABAQUS were used for elasto-plastic time-history analysis. According to SAUSAGE calculation, the maximum displacement in the X-direction and Y-direction of the structure is 0-248m and 0-183m respectively, and the maximum interlayer displacement angles in the X-direction and Y-direction are 1/271 and 1/237 respectively. The ratio of the maximum base  shear force in the X-direction and Y-direction  to the base shear force under small earthquake calculated by CQC method is 3-6 and 3-9 respectively, and the damage condition of the components meets the relevant requirements of the performance target D under  large earthquake. At the same time, by comparing the analysis  results of ABAQUS and SAUSAGE, the total mass, characteristic period, displacement curve, interlayer displacement angle curve, base shear force  time history curve and component damage are basically the same, and the accuracy of SAUSAGE analysis results is verified. In addition, through ABAQUS calculation, the shear wall part began to consume energy at 6s, and the frame part began to consume energy at 13s, indicating that the shear wall in the frame shear structure playes the first anti-seismic defense effect, and the frame part playes the second anti-seismic defense functions.
