Abstract: The steel structure roof of Qionghai Stadium has an elliptical plane， with a long axis of 260 m and a short axis of 218 m， whose main structure is a canopy structure-space structure system. in the report， in order to ensure the safety of the stadium during the whole service life， the health monitoring program of Qionghai Stadium roof structure was put forward. Midas Gen finite element software was used to perform the mechanical analysis of the typical components of the steel roof of the stadium， and the stress distribution and displacement of the structure under specific working conditions were obtained. Based on the mechanical analysis data， the monitoring items such as strain， displacement， acceleration， wind direction and speed were selected from the load and environment， the overall and local response of the structure， and the selection of sensors and the layout of monitoring points were carried out. The program can be used for the safety warning of the steel structure roof of the stadium， the condition of the roof structure can be determined in time， and provide the reliable guarantee for the normal operation of the stadium.
