［摘要］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。

Abstract:The concrete structure of the Guiyang Olympic Center main stadium, of which the west stand for the steel structure, is  the concrete inclined frame with 6 meters outwardly cantilever, adopts Y form column. In the whole calculation, the path toward the frame adopts a slice frame to carry on internal force calculation analysis and summarize internal force distributing orderliness of inclined frame. According to internal force analysis result, composite beam and column are adopted in the structure partly. Design is carried on a composite member of tension bent and two way off centre compressed.Also carry on finite element analysis to the key node of Y form column.The super long concrete stand structure, according to calculating result, adopts some structure measures to solve the concrete temperature stress problem. Because of the higher pull and level force, the steel cantilever shed foundation fall to the ground adopts pile foundation.
Keywords:staclium; fulcrum cantilever; earthquake action; super long; internal force; node; anti-pull and level force pile
