(1.College of Civil Engineering Yancheng Institute of Technology Yancheng Jiangsu 224051 China; 2.Key Laboratory of Concrete and Prestressed Concrete Structure of Ministry of Education Southeast University Nanjing Jiangsu 210096 China) Abstract: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 parative 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...
