结构的诗意表达——中国科学技术大学高新园区体育馆设计

Poetic Expression of Structure——Design of Gymnasium in High Tech Park of University of Science and Technology of China

中国科学技术大学高新园区体育馆支撑大跨屋顶的树杈结构象征大学的林荫大道,枝繁叶茂,树杈结构的立体交错象征中国科学技术大学学科交叉的精神。体育馆屋面跨度64 m,结构形式上采用树杈状立柱+张弦网格屋面体系,巧妙利用复合结构中树杈状立柱缩小中心张弦结构受拉区域的跨度。同时,树杈结构也能平衡掉屋面拱壳结构的侧推力。

The branch structure supporting the large-span roof symbolizes the University Boulevard with luxuriant branches and leafs.The three-dimensional crisscross of the branch structure symbolizes the spirit of interdisciplinary in the University of Science and Technology of China.The roof span is 64 meters.In terms of structural form,the system of branch column+tension chord grid roof is used to reduce the span of the tension area of the central tension chord structure by ingeniously using the branch column in the composite structure.At the same time,the branch structure can also balance the side thrust of the roof arch shell structure.
