全国大学生结构设计竞赛是土木工程学科培养大学生创新精神、团队意识和实践能力的最高水平学科竞赛。第十届全国大学生结构设计竞赛与往届相比，命题中引入了刚柔并济的思想，除了要求结构具有足够的承载力，还对结构正常使用极限状态下结构的跨中挠度做了限制。从第十届全国大学生结构设计竞赛特等奖作品入手，分析特等奖作品的结构选型和结构优化方法，以期为学生准备结构设计竞赛提供参考。

National Structural Design Contest for College Students is the highest-level discipline contest for learners of Civil Engineering, which aims to cultivate and enhance their innovative spirit, group consciousness and practical abilities. Compared with previous contests, the 10th National Structural Design Contest for College Students paid more attention to hardness and softness, limitation on mid-span deflection except its previous request on sufficient capacity. Based on the grand prize work of the 10th National Structural Design Contest for College Students, this thesis mainly makes an analysis on its choice of structural styles, and optimization methods of structure. The study of structural design and optimization methods of the grand prize work in this thesis may provide some reference value for structural design contest in the future.
