塔里木大学体育馆结构设计

Structural design of Tarim University Gymnasium

塔里木大学体育馆位于新疆阿克苏地区阿拉尔市。根据建筑功能及外观形态可划分为体育馆和游泳馆两个独立的结构单元。两馆主体结构均采用周边带交叉斜柱的钢框架结构,屋盖采用双层正放四角锥钢网架结构。体育馆屋盖网架平面尺寸93.8m×77.8m。体育馆周边斜柱从看台层(亦为斜柱交叉点)至柱顶长度达到19m,中间无其他约束,面外稳定问题突出。本文介绍了塔里木大学体育馆结构设计概况,并重点介绍了体育馆大跨度屋盖结构选型、边界条件的设置以及周边交叉斜柱的受力特性、节点细部构造等内容。为同类建筑的设计提供参考。

Tarim University Gymnasium is located in Alar City,Aksu Prefecture,Xinjiang.According to the function and appearance of the building,it can be divided into two independent structural units,the gymnasium and the swimming pool.The main structure adopts a steel frame structure including cross inclined columns,and the roof is square pyramid space grid structure.The length of the inclined column of the gymnasium from the stand floor(also the intersection of the inclined column)to the top of the column is 19m,with no other constraints in the middle,and the problem of out-of-plane stability is prominent.This paper introduces the general situation of the structural design of the Tarim University Gymnasium,and focuses on the selection of the large-span roof structure of the gymnasium,the setting of boundary conditions and the the stress mechanism and joint structure of the cross-inclined column.This paper can also provide reference for the design of similar buildings.
