摘要：The Swimming and Diving Hall in Qingdao Sports Center is constructed for the 11th National Games. As a complex grid structure with a long-span steel roof, its construction is difficult to control. The pulling haulm to promotion method is employed in the construction of this grid structure. Detailed finite element analyses are carried out in the promoting and unloading process to guide the safe construction of this structure. The construction is monitored wirelessly by using chordal strain gauges, static level meters and displacement gauges, thus the vertical displacements of grid structure, the displacements and internal forces of bearing are measured. At the same time, the finite element analyses for this structure are performed in detail. It is shown that the monitoring results are in good agreement with the results of finite element analyses in the unloading process, demonstrating that Qingdao Sports Center Swimming and Diving Hall is unloaded successfully, and the finite element analysis results are correct.
