Fu Xinzhi' Wu Wenping' Wang Wenxing (1.Jiangsu Huning Steel Mechanism Co.Lsd. Yixing Jiangsu 214231 China; 2.College of Civil and Transportation Engineering Hohai University Nanjing Jiangsu 210098 China) Abstract:Due to the large span plex structure form high steel consumption and other characteristics there are a series of problems of steel structure projects The effect of‘path’and*time' in the construction process have a great influence on the stress state and geometric shape in closure of the structures.Reasonable construction scheme should minimize the residual stress due to construction after closure of the structures on the premise of the safety of construction.Based on the construction and installation of steel roof in Jiangsu Grand Theater drama hall bining with the structure characteristics and construction conditions of d...
