摘要

为评价成都某框架-剪力墙超限项目的大震安全性,采用SAUSAGE和ABAQUS进行弹塑性时程分析。通过SAUSAGE计算,结构顶部X向和Y向最大位移分别为0.248m和0.183m,X向和Y向最大层间位移角分别为1/271和1/237,X向与Y向最大基底剪力与小震CQC法基底剪力的比值分别为3.6和3.9,构件损伤情况均满足大震下性能目标D的相关要求。同时,通过ABAQUS与SAUSAGE分析结果对比,总质量、特征周期、位移曲线、层间位移角曲线、基底剪力时程曲线以及构件损伤基本相同,验证了SAUSAGE分析结果的准确性。此外,通过ABAQUS计算,剪力墙部分在6s时开始进行耗能,框架部分在13s时开始进行耗能,说明框剪结构中剪力墙起到了第一道抗震防线作用,框架部分起到了第二道抗震防线作用。
        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 0.248 m and 0.183 m 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 6 s, and the frame part began to consume energy at 13 s, 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.
