Abstract: Kaifeng Sports Center Gymnasium is mainly composed of three parts: competition hall, basketball training hall and warm-up hall. It is a large-scale comprehensive multi-functional hall. Combined with the characteristics of building layout, the lower structure adopts reinforced concrete frame-shear wall structure, the upper part of the warm-up hall adopts two-way orthogonal steel truss, and the upper roof adopts two-way orthogonal vertical plane tube truss. The upper roof and the lower main structure are connected by vibration isolation bearings. The structural design of the gymnasium was comprehensively expounded in terms of the structural characteristics, foundation, main structure, large-span floor of the basketball training hall and the steel structure roof. Various indexes of the overall model of the structure under wind load and earthquake were calculated by YJK software. MIDAS Gen was used to analyze the comfort of the large-span floor of the basketball training hall under different pedestrian load conditions. The vertical displacement of the steel roof was analyzed, and the strengthening measures for the super-long structure were introduced. The results show that the two ends of the large-span floor of the basketball training hall and the frame columns are connected by rigid connection, which has strong integrity, can reduce the height of the truss, ensure the indoor clear height, and can also solve the problem of comfort. The structure is safe and reliable, and all indicators meet the specification requirements.
