| Abstract: | An office building extend project is to add one floor steel structure on its original roof and the new roof is a prestressed cable arch structure. Engineers adopted the ANSYS software to make a construction simulation calculation for this prestressed cable arch, analyzed nonlinear features of this prestressed cable arch structure in construction process, and guided the practical construction procedure according to simulation calculation results. In this article, authors also state some construction technologies of the prestressed cable arch structure including the steel cable tension technology, and stress monitoring and control technology and so forth. |
