Abstract
Ningxia Helan Mountain stadium the bottom grandstand of which is steel reinforced concrete frame shear wall structure, the top canopy of which is space steel truss structure system. Using SAP2000 (V9.1.6 version) and MIDAS (V7.1.2 version) software, to have an elasticity check analysis to the overrall structure. Discussion the vibration characteristics and seismic performance of the stadium steel canopy; According to computing and analysising the model, taking normative inspect, the consequence show that the structure can meet the bearing capacity, the stress ratio of the majority position are not more than 0.7, and the stress ratio of force greater position are about 0.95. This wave-shaped canopy structure is excellent, is good to the applicability of architectural form, and can be as a reference for the similar stadium.
