郑州某奥体中心方案结构可行性设计与分析

Structure feasibility design and analysis of an Olympic Center in Zhengzhou

郑州某奥体中心方案包括体育中心、体育馆和游泳馆3个子项,地上结构最大平面尺寸351m×306m。本文首先结合建筑方案对体育中心子项索网屋面做法的结构可行性进行详细论证。随后对体育中心子项自平衡巨型拱结构的结构可行性做了系统分析。同时对体育中心子项看台顶部承压拱桁架做法做了结构概念设计。最后对体育馆、游泳馆子项的大跨度屋面形式进行了可行性设计及分析论证。研究及设计结果表明:通过选用合理的结构设计方案,提出的的钢结构屋面基本可以满足规范相关设计要求,结构方案判别可行。

An Olympic Center in Zhengzhou includes 3 program which are sports center,gymnasium and swimming pool respectively,and the maximum plane dimension of the ground structure is 351 m × 306 m.Firstly,combined architecture scheme,the structure feasibility of the cable network roof of sports center was explained.Then the structure feasibility of the self-balancing giant arch structure of sports center was introduced systematically.At the same time,the structural conceptual design of the pressure arch truss above the stands of the sports center was introduced.Finally,structure feasibility of the large span roof of the stadium and the swimming pool was emphatically presented.Research and design results show that,by using reasonable structural design,the practice of steel roofing which is presented can meet the design requirements related to the specifications,and the structural plan is feasible.
