国内首幢CFRP索悬挂建筑结构施工技术

Construction Technology of the First CFRP Cable Suspended Structure in China

目前,对于大跨网壳、桥梁、隧道等重要结构进行施工过程分析的文献已有不少,但高层、超高层、特殊结构的结构施工过程分析的文献却较少。介绍了国内首幢CFRP索悬挂建筑结构施工方案的确定,通过不同吊装方案时悬挂大梁内力的对比分析,确定吊索张拉方案;运用ANSYS有限元软件对施工过程进行数值模拟,确定各吊索的张拉控制力。计算分析表明,悬挂结构试点工程的施工分析,可以较为准确地反映出结构的内力,变形情况,比选出较优方案。

Currently,there are many analysis on construction process of the documents about important structure such as span network shells,bridges,tunnels,etc. But there is rare about high-rise structure,ultra-high-rise structure and the special structure. Firstly,the construction program of the first CFRP cable suspended structure in China is confirmed. Then,sling tension scheme is determined through the comparative analysis of hanging beams internal forces in different lifting programs. Finally,the sling tension control is ascertained by using ANSYS software to simulate the construction process. The calculation result indicates that construction analysis of the pilot project can reflect the inner force and deformation condition,and select the optimum solutions.
