A new way of anchoring steel towers atop buildings and structural analysis;
新型楼顶钢塔的锚固方式及其结构分析
In recent years, the steel towers atop buildings have been adopted in many regions in our country with the development of communication business.
目前国内这种组合结构体系的动力性能研究得较少,也尚无统一的抗震鉴定标准和设计规范可循,所以研究地震作用时楼顶钢塔的动力特性以及钢塔和主体结构间的相互影响作用成为工程实践不断发展提出的迫切要求。
Under the different earthquake waves had time history analysis and comparison with three modes: the mode without steel tower atop building,the mode only with the steel tower atop building and with a TMD system of the steel tower atop building.
本文利用有限元软件SAP2000建立了某四层钢框架模型,对其未设置屋顶钢塔、仅设置屋顶钢塔及设置屋顶钢塔和TMD三种模型进行了不同地震波下的时程分析和比较。
