摘　　要：为研究内嵌墙板对模块化钢框架的刚度贡献,采用Midas/gen有限元软件建立了带内嵌墙板模块化钢框架计算模型进行抗侧力学性能分析。推导了带内嵌墙板的钢框架模型抗侧刚度计算公式,并与有限元结果进行对比分析,研究结果表明:在水平力作用下内嵌墙板与钢框架协同工作可分为加载初期的协同工作阶段以及钢框架变形后的内嵌墙板支撑阶段;带有内嵌墙板的钢框架的抗侧刚度和极限承载力主要由内嵌墙板承担;考虑内嵌墙板模块化钢框架抗侧刚度计算公式(10)与有限元模型计算结果相比,二者误差小于10%;考虑内嵌墙板刚度贡献的钢框架,其极限承载力和抗侧刚度都得到了显著提升。In order to study the stiffness contribution of embedded wallboard to modular steel frame,Midas/gen finite element software is used to establish the calculation model of modular steel frame with embedded wallboard to analyze its lateral mechanical properties.The formulas of the model for calculating the lateral stiffness of steel frame with embedded wallboard are derived and compared with the finite element results.The results show that the cooperative work of embedded wallboard and steel frame under horizontal force can be divided into the cooperative work stage during initial loading and the support stage of embedded wallboard after steel frame deformation.The lateral stiffness and ultimate bearing capacity of steel frame with embedded wallboard are mainly borne by the embedded wallboard.Compared with the results of the finite element model,the error of formula(10)which is used to calculate the lateral stiffness of modular steel frame with embedded wallboard is less than 10%.The ultimate bearing capacity and the lateral stiffness of steel frame taking into account the stiffness contribution of embedded wallboard are significantly improved.
