Abstract

The construction procedure of Jiangnan University new campus stadium is complex. During the construction process, the complicated load combination, the geometrical shape and boundary of long-span structure are greatly different between the construction process and the normal usage stage. To assure the safety of the construction process, the displacement monitoring analysis is performed on the stadium reticulated shell structure construction. The optical apparatus KONI007 made in France is used in the vertical displacement monitoring process with 2nd level measure precision. The displacement locations are introduced in the paper and the monitoring data process analysis is also done. To investigate the displacement and stress distribution of the roof structure, the three dimensional finite element analyses is performed. The monitoring data analysis and finite element analyses result show that the deformation of the chords are evenly distributed and the elastic support has fewer elastic deformation to decrease the horizontal push force on the concrete column and to adjust the reticulated shell chord internal force. The reticulated shell construction procedure is reasonable.
