Abstract：
The steel roof of exhibition hall in phase II of an Exhibition Center project in Xinjiang is a truss string structure, and the elevation of each truss frames of the exhibition hall in Zone B is different. To realize safety control of slippage construction of roof system with column in Zone B, the general finite element software midas Gen was used for simulative analysis on construction of truss string truss roof structure. This paper introduced the cable stretching control, non-synchronization of slippage with column and influence of wind load on construction. It was found that the truss string structure satisfies various control indices in truss string stretching during slippage with column; the allowable value of slippage non-synchronization reduced after the increase of truss frame number, so accurate synchronization control was required during slippage construction; wind load produced very little influence of the slippage construction.
