The long term monitoring analyses of a grid structure for swimming and Diving Hall in Qingdao Sports Center

Swimming and Diving Hall in Qingdao Sports Center is the 11th National Games match field for swimming and diving. In view of complex grid structure for big-bay steel roof structure of Qingdao Sports Center Swimming and Diving Hall, construction is very difficult and not easy to control. The grid structure is monitored wirelessly by using chordal strain gauges, static level meters and displacement gauges during unloading and in use, then the vertical displacements of grid structure, the displacements and internal forces of bearing are measured. The monitoring results suggest that the structural design of grid is rational. In addition, through the long-term monitoring, we found that the strain and displacement of the grid get stable gradually, and show that the grid structure is safe. The results show that this wireless monitoring project is reliable and safe for similar large and complex grid structure.
