【摘要】：恒大國(guó)際金融中心G區(qū)裙房地上5層,主體結(jié)構(gòu)高度29.0m,采用帶支撐的鋼框架結(jié)構(gòu)體系,局部采用大跨度桁架轉(zhuǎn)換做法。首先結(jié)合建筑方案及經(jīng)濟(jì)性分析說明了主體結(jié)構(gòu)的體系選型方案。隨后,系統(tǒng)介紹了項(xiàng)目設(shè)計(jì)過程中針對(duì)塔樓結(jié)構(gòu)平面不規(guī)則、豎向不規(guī)則及其他不規(guī)則項(xiàng)選用的計(jì)算措施和設(shè)計(jì)措施。同時(shí),對(duì)主體結(jié)構(gòu)設(shè)計(jì)選用的性能化設(shè)計(jì)方法進(jìn)行了具體陳述。最后,對(duì)大跨度桁架轉(zhuǎn)換結(jié)構(gòu)的補(bǔ)充計(jì)算方法和結(jié)構(gòu)加強(qiáng)措施進(jìn)行了重點(diǎn)介紹。研究及設(shè)計(jì)結(jié)果表明:通過選用合理的計(jì)算措施和設(shè)計(jì)措施,原結(jié)構(gòu)的不規(guī)則性得到有效控制,結(jié)構(gòu)各項(xiàng)計(jì)算指標(biāo)可以較好地滿足規(guī)范要求,結(jié)構(gòu)安全、可靠,結(jié)構(gòu)設(shè)計(jì)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.
