［摘要］貴陽(yáng)奧體中心主體育場(chǎng)看臺(tái)混凝土結(jié)構(gòu)，西看臺(tái)屋蓋鋼結(jié)構(gòu)的上支點(diǎn)支承在混凝土斜框架向外懸臂6m處，設(shè)計(jì)中采用Y型柱。在整體計(jì)算基礎(chǔ)上，徑向框架采用單榀框架進(jìn)行內(nèi)力計(jì)算分析，給出了斜框架的內(nèi)力分布規(guī)律。根據(jù)內(nèi)力分析結(jié)果，部分結(jié)構(gòu)采用型鋼混凝土梁柱，并進(jìn)行了型鋼混凝土拉彎構(gòu)件及雙向偏壓構(gòu)件的設(shè)計(jì)，并對(duì)Y型柱的關(guān)鍵節(jié)點(diǎn)進(jìn)行有限元分析。超長(zhǎng)混凝土看臺(tái)結(jié)構(gòu)，在計(jì)算基礎(chǔ)上，采取在看臺(tái)梁板設(shè)縫等構(gòu)造措施解決超長(zhǎng)混凝土的溫度應(yīng)力問題。落地鋼挑篷基礎(chǔ)由于存在較大的向上拉力及水平力，采用抗拔及抗水平力樁解決。

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
