为系统研究带边框组合柱剪力墙组合结构的抗震性能，基于分层壳单元与非线性纤维梁单元，在ABAQUS 软件中进行用户材料模型子程序二次开发。用分层壳单元模拟剪力墙，纤维梁单元模拟外围组合框架，分别对钢管混凝土组合框架、带钢管混凝土边框柱及型钢混凝土边框柱的组合剪力墙进行低周往复加载试验数值模拟。计算、试验结果总体吻合较好。在此基础上，对比分析该类组合剪力墙滞回性能、受力特征及破坏特征，数值模拟获得墙板在典型时刻的裂缝分布等与实测结果接近。研究表明，采用分层壳单元与纤维梁单元能较准确、有效模拟带边框柱组合剪力墙体系的滞回性能，亦能较好描述剪力墙裂缝发展情况。该方法可为实现高层建筑钢与混凝土混合结构体系抗震性能有效、准确的数值模拟分析提供参考。

In order to study the seismic performance of the composite structure with RC shear walls and composite frames,the secondary development in ABAQUS was performed to achieve the user materials model using the user subroutine based on layered shell elements and nonlinear fiber beam elements.The RC shear walls and composite frames were simulated by layered shell elements and fiber beam elements respectively.A numerical simulation was carried out to study the cyclic performances of composite frames with concrete-filled steel tubular(CFST)columns,mixed structures with CFST columns and steel reinforced concrete (SRC)columns and RC shear walls,respectively.The results obtained from the calculation are in good agreement with those from the experiment.The hysteresis behavior character and failure modes of the composite shear walls were analyzed and compared between the results of test and simulation,and it is shown that the typical crack distribution of the walls in test is similar to the numerical results.The research shows that the layered shell element and fiber beam element can simulate hysteretic behaviors of the composite shear walls more accurately and effectively,and it can describe the development of shear crack reasonably.
