| 为改善钢框架 支撑结构体系中支撑易屈服问题，简化钢框架 钢板剪力墙结构体系中剪力墙的受力，结合钢框架 钢板剪力墙结构体系中钢板剪力墙“拉力带”受力特性和两侧开缝钢板剪力墙简化模型，提出了一种新型结构体系——钢框架 桁架结构体系。对钢框架 桁架新型结构体系进行了介绍，通过SAP2000建立了钢框架 桁架结构体系模型，对这一新型结构体系进行了模态分析、反应谱分析和线性时程分析并与钢框架 钢板深梁结构体系和纯钢框架结构体系进行了对比。分析结果表明钢框架 桁架结构体系有较高结构抗侧刚度；在地震作用下，钢框架 桁架结构体系与钢框架 钢板深梁结构体系具有相似的动力特性，在一定条件下利用钢框架 桁架结构体系简化和等效钢框架 钢板深梁结构体系是合理的。 |

| A new steel frame infilled by truss structure system is presented in this paper to solve the yield of brace and simplify stress of steel plate shear wall. The new structure is presented according to tension field behavior of steel plate shear wall in steel frame steel plate shear wall structure system and simplified modal for steel plate shear wall slotted at edge. The new steel frame infilled by truss structure system is introduced and its modal is set up through SAP2000. The modal analysis, response spectrum analysis and liner time history analysis of the new structure system are carried out, and the analysis results are compared with steel frame steel plate deep beam structure system and steel frame structure. The analysis results indicate that: steel frame infilled by truss structure gets a greater lateral stiffness and similar dynamic characteristics to steel frame steel plate deep beam structure. It’s reasonable to simplify and equivalent steel frame steel plate deep beam with steel frame infilled by truss structure system under certain conditions. |
