| 摘 要： | 以广州珠江城超高层大厦为例,结合施工过程定期对该楼23～27层外伸及带状钢结构桁架进行现场应力应变监测.同时,采用有限元软件ETABS中的顺序施工模块功能,对该楼模型进行施工过程数值模拟分析.监测结果表明：钢结构是安全的;模拟分析理论值与实测数据吻合较好,表明有限元模拟分析计算模型和方法的正确性.研究成果可作为广州珠江城大厦安全施工控制方面的一项重要评估指标,同时对同类工程具有参考价值.

| Abstract: | Taking the Pearl River Building in Guangzhou as an example,the on-site construction health monitoring system was established during its construction stage.The stress and strain measurements on the key elements of outrigger and belt trusses between the 23-27 floors of the building were conducted.Meanwhile,the finite element software ETABS was utilized to conduct the numerical structural analysis for construction simulation during its different construction stages.Comparison between field measurement and numerical analysis showed that numerical simulation results have good agreements with the measured data,which indicated that the proposed construction mechanics analysis procedures in this paper are valuable for the construction monitoring and control for this super tall building.The method could also be used as the practical references for the similar high-rise buildings＇ design and construction. |
