STRUCTURAL DESIGN AND HEALTH MONITORING OF JINAN OLYMPIC SPORTS CENTER

Jinan Olympic sports center is the primary venue for the 2009 National Sports Games. The design characteristics and structure health monitoring and monitoring results of Jinan Olympic sports center steel structure are introduced. The sports center includes a Stadium and three Gymnasiums, namely Stadium, Gymnasium, Swimming Gymnasium and Tennis Gymnasium. The stadium adopts a suspended lattice shell, and the others are folding space steel truss structure. Engineering practice shows that the assembled total model analysis of large spatial reticulated structures is important, the simplified calculation model of node is controlled by rigidly and hinged connection; the finite element analysis must be performed for the nodes of a complex space structure also. For a suspended lattice shell, the key is the establishment of the prestress system and the choice of the prestress size, the prestress value from the matrix equilibrium theory is proved to be feasible and effective. The key bar strain was monitored using Fiber Bragg Grating (FBG) sensor, and also achieved higher accuracy and better stability, and it can be applied to other similar structure monitoring.
