德阳市体育馆根据建筑造型及功能要求,屋盖采用了双曲抛物面双层钢网壳结构.屋盖投影平面呈菱形,边长74.67m.对角线长105.60m.通过对双层问壳结构的受力特点,杆件布置形式,网壳厚度的确定及网壳与悬索结构对边缘构件的影响等方面的论述,阐明了结构设计方案的确定原则.另外进行了结构内力分析,并介绍了支座构造,钢材指标等.
Deyang Gymnasium has adopted a double-curvature parabolic double steel mesh shell structure according to architectural modeling and functional requirements. The roof projection plane is diamond-shaped, with a length of 74.67m and a diagonal length of 105.60m. It passes through the double-layer shell structure. The stress characteristics, the arrangement of the rods, the determination of the thickness of the shell, the influence of the shells and suspensions on the marginal elements, etc., clarify the principles for the determination of the structural design. In addition, the analysis of the internal forces of the structure is introduced and introduced. Support structure, steel indicators, etc.
