［摘要］对天津国际贸易中心高层框架-支撑钢结构的建设和加固方案进行了介绍。建立了加固前和加固后结构整体模型，并对施工过程进行了模拟，对比分析了关键部位施工过程中的应力和位移。对整体结构在加固前和加固后使用阶段的重要设计指标进行了对比分析。在施工过程中，对加固柱和未加固柱进行了现场监测，监测结果表明，加固效果良好，能够保证施工的安全。［关键词］高层框架-支撑钢结构; 加固; 施工模拟; 施工监测中图分类号：文献标识码：A 文章编号：1002-848X(2016)05-0008-05
Analysis on reinforcement effect of high-rise steel braced frame structure of Tianjin International Trade CenterDu Yansheng1, Chen Zhihua1, Zhao Zhongwei1, Liu Xiaoke1, Lü Huangbing2(1 School of Civil Engineering, Tianjin University, Tianjin 300072, China; 2 China Construction Steel Structure Co., Ltd., Beijing 100089, China)Abstract:The construction and reinforcement schemes of high-rise steel braced frame structure of Tianjin International Trade Center were introduced. The overall models of the structure before and after reinforcement were established, and simulation of the construction procedure was operated to compare the stress and displacement of the key positions in construction process. Key design indices of the structure in service stage before and after reinforcement were compared and analyzed. Field monitorings of original columns and reinforced columns were conducted, and the monitoring result proves that reinforcement is effective to guarantee the safety during the construction.Keywords:high-rise steel braced frame structure; reinforcement; construction simulation; construction monitoring
