【摘要】：恒大國際金融中心G區(qū)裙房地上5層,主體結構高度29.0m,采用帶支撐的鋼框架結構體系,局部采用大跨度桁架轉換做法。首先結合建筑方案及經濟性分析說明了主體結構的體系選型方案。隨后,系統(tǒng)介紹了項目設計過程中針對塔樓結構平面不規(guī)則、豎向不規(guī)則及其他不規(guī)則項選用的計算措施和設計措施。同時,對主體結構設計選用的性能化設計方法進行了具體陳述。最后,對大跨度桁架轉換結構的補充計算方法和結構加強措施進行了重點介紹。研究及設計結果表明:通過選用合理的計算措施和設計措施,原結構的不規(guī)則性得到有效控制,結構各項計算指標可以較好地滿足規(guī)范要求,結構安全、可靠,結構設計可行。
[Abstract]:Evergrande International Financial Center G area has five floors on the ground and the main body structure is 29.0m.The steel frame structure system with support is adopted, and the transformation of large span truss is adopted locally. Firstly, the system selection scheme of the main structure is explained by combining the building scheme and the economic analysis. Then, the calculation measures and design measures for irregular plane, vertical irregular and other irregular items of tower structure in the process of project design are systematically introduced. At the same time, the performance design method used in the main structure design is described in detail. Finally, the supplementary calculation method and structural strengthening measures of long span truss transfer structure are introduced emphatically. The research and design results show that the irregularity of the original structure can be effectively controlled by selecting reasonable calculation measures and design measures, and the calculation indexes of the structure can better meet the requirements of the code, the structure is safe and reliable, and the structural design is feasible.
