摘要：开封市体育中心体育馆主要由比赛馆、篮球训练馆和热身馆三部分组成，属于大型综合性多功能场馆。结合建筑布置特点，下部结构采用钢筋混凝土框架-剪力墙结构，热身馆上空采用双向正交钢桁架，上部屋盖采用双向正交正放平面管桁架，上部屋盖与下部主体结构之间通过隔震支座连接。针对结构特点、地基基础、主体结构、篮球训练馆大跨楼盖以及钢结构屋盖对体育馆的结构设计进行了全面的阐述。利用YJK软件，计算了结构整体模型在风荷载、地震作用下的各项指标；采用MIDAS Gen对篮球训练馆在不同人行荷载工况下的大跨楼盖舒适度进行了分析；对钢屋盖的竖向位移进行了分析，并对超长结构的加强措施进行了介绍。结果表明：篮球训练馆大跨楼盖两端与框架柱采用刚接连接，整体性强，可减小桁架高度，保证室内净高，亦可解决舒适性问题。结构安全可靠，各项指标均满足规范要求。

Structural design of Kaifeng Sports Center Gymnasium
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.
