摘　　要：利用ABAQUS有限元软件,对一榀钢框架和一榀生土填充墙钢框架的抗剪性能进行对比分析,在此基础上对生土填充墙钢框架的抗剪性能进行参数分析.对比分析结果表明:生土填充墙钢框架是一种较好的抗侧力结构体系,其初始刚度和抗剪承载力均明显高于纯钢框架,并且生土填充墙可以降低钢框架屈服后刚度退化严重的不利影响;参数分析结果表明:框架柱轴压比、墙体高厚比和钢框架梁柱线刚度比是影响生土填充墙钢框架抗剪性能的主要因素.推导了生土填充墙钢框架初始刚度和抗剪承载力的理论计算公式。Comparison of shear performance with a steel frame and a steel frame with an adobe infilled wall is made in this paper by using finite element analysis software ABAQUS. On this basis, parameter analysis on shear performance of steel frames with ado- be infilled walls are carried out. The results indicate that the initial stiffness and shear capacity of steel frames with adobe infilled walls are higher than pure steel frames and the adobe infilled walls can reduce the adverse effect on the stiffness degradation of pure steel frames after yielding. The axial compression ratio of columns, depth-thickness ratio of walls and beam-to-column linear stiffness ratio of steel frames are the main factors influencing the shear performance of steel frames with adobe infilled walls. The- oretical calculation formulas for initial stiffness and shear capacity of steel frames with adobe infilled walls are derived. The calcu- lated results turn out to agree with the finite element analysis well.
