摘要
为适应大跨度钢结构的应用和发展,在混合式交错桁架结构的基础上提出了一种更先进的钢结构-交错桁架钢框架-钢板剪力墙结构体系。然后,运用SAP2000有限元软件,对两个不同的跨度分别建立4个计算模型,对其进行反应谱分析、时程分析、用钢量分析等,得出新型结构体系比传统混合式交错桁架具有更优越的抗震性能和经济价值。
In order to adapt to the development and use of long-span steel structure,a new structural system of staggered-truss steel shear wall is proposed, which is based on the hybrid staggered-truss system and is more advanced than it. Then four calculation eases with two different spans are established. Response spectrum analysis, nonlinear time history analysis and steel quantity analysis are carried on by sap2000. Finally, it comes to a conclusion that the new structure has a better seismic performance and economical value than the traditional one.
