Research on several key technologies for structural construction of main stadium for the Universidad Sports Centre

The roof of the main stadium for the World Universidad Games adopted the single-layer folded-plane lattice shell structure.It is necessary to analyze the internal force and deformation of main stadium for the World Universidad Games during the construction process by using the method of constructional mechanics.The influences of the supports were considered by finite element analysis.This paper analyzed the process of lifting and summarizes the difficulties during the construction process.Moreover,the nodes of structure were researched.The analytical results show that the support has significant effect on structure and set the position of stress monitoring on the supports can also effectively guide the construction.The sizes of lifting rope are determined by the allowable stress method.Through adjustment by people can solve the problem of stability effectively.It is feasible to lock the lifting rope on bars by rings.From the analysis,it is believed that the peak stress does not exceed the yield strength for cast steel nodes,and this has the high security reserves.
