［摘要］對天津國際貿易中心高層框架-支撐鋼結構的建設和加固方案進行了介紹。建立了加固前和加固后結構整體模型，并對施工過程進行了模擬，對比分析了關鍵部位施工過程中的應力和位移。對整體結構在加固前和加固后使用階段的重要設計指標進行了對比分析。在施工過程中，對加固柱和未加固柱進行了現(xiàn)場監(jiān)測，監(jiān)測結果表明，加固效果良好，能夠保證施工的安全。［關鍵詞］高層框架-支撐鋼結構; 加固; 施工模擬; 施工監(jiān)測中圖分類號：文獻標識碼：A 文章編號：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
