Structural Design of Jingzhou Gymnasium

该文介绍了荆州市体育馆结构选型与布置、节点设计和结构分析。下部主体结构为钢筋混凝土框架结构,结构总长124.2m,没有设缝,通过构造措施和温度计算解决混凝土开裂问题;钢屋盖提出了三种结构体系:辐轮式张弦桁架结构、径环向布置的平面桁架和棋盘式布置的立体桁架,并进行了比较,其中棋盘式布置的立体桁架与建筑内外空间形态相适宜,简洁美观,且经济性良好,得到了建筑师的认可。周边采用树枝状格构式钢柱和折板空间桁架结构,与建筑造型和谐统一。

The paper introduced the structural scheme selection and layout, joint design, structural analysis of Jingzhou gymnasium. Except the roof and the curtain wall, the gymnasium＇s main structure is the reinforced concret frame structure, with 124.2m length and without any structural joints. Construction measures and thermal action calculation are applied to prevent concret cracking. Three kinds of the roof structure, which are the radial truss string structure, the radial plane truss structure and the checker board arrangement of spatial truss, were proposed and compared with each other, the checker board arrangement of spatial truss, which is simple, beautiful, saving and appropriate to building exterior and interior space form, was favored by the architects. The tree branch-shaped latticed column and the folded plane type steel truss, coordinated with the surrounding architectural style, distributes in the outer circle.
