贵阳奥体中心主体育场看台混凝土结构,西看台屋盖钢结构的上支点支承在混凝土斜框架向外悬臂6m处,设计中采用Y型柱。在整体计算基础上,径向框架采用单榀框架进行内力计算分析,给出了斜框架的内力分布规律。根据内力分析结果,部分结构采用型钢混凝土梁柱,并进行了型钢混凝土拉弯构件及双向偏压构件的设计,并对Y型柱的关键节点进行有限元分析。超长混凝土看台结构,在计算基础上,采取在看台梁板设缝等构造措施解决超长混凝土的温度应力问题。落地钢挑篷基础由于存在较大的向上拉力及水平力,采用抗拔及抗水平力桩解决。
The main stadium of Guiyang Olympic Sports Center Stadium stands the concrete structure. The upper fulcrum of the western section stand roof steel structure is supported at 6m to the cantilever of the concrete diagonal frame. The Y-shaped column is adopted in the design. On the basis of the overall calculation, the radial frame is calculated and analyzed by the single frame, and the internal force distribution of the diagonal frame is given. According to the results of internal force analysis, the part of the structure is made of SRC beam columns, and the design of steel-reinforced concrete bending members and bidirectional biasing members is carried out. The key nodes of Y-shaped columns are analyzed by finite element method. Ultra-long concrete stands structure, on the basis of calculation, to take the stand in the bleachers and other structural measures to solve the temperature stress of long concrete. Ground steel canopies based on the existence of a large upward pull and horizontal force, the use of anti-pull and horizontal pile solution.
