［摘要］深港西部通道旅檢大樓是一棟超長、體型復(fù)雜的巨型鋼-混凝土混合結(jié)構(gòu)，鋼柱傾斜，鋼梁跨度大、截面小。港方使用的一側(cè)需同時符合中國大陸和中國香港的規(guī)范，在結(jié)構(gòu)選型、抗震設(shè)計、抗風(fēng)設(shè)計及施工上都存在難點。設(shè)計時在深港分界處設(shè)置了防震縫，將建筑物分成兩個抗震單元，并選取了合理的結(jié)構(gòu)布置方式。進行了小震彈性分析，結(jié)果表明計算指標(biāo)均能符合規(guī)范要求。對抗震分析中的關(guān)鍵問題、巨型鋼結(jié)構(gòu)穩(wěn)定性問題進行了詳細的分析，在關(guān)鍵的部位和節(jié)點采取了有效的措施。通過風(fēng)洞試驗得到準確的風(fēng)壓系數(shù)和風(fēng)振系數(shù)，并據(jù)此進行了抗風(fēng)設(shè)計。對施工的難點提出了解決方法，供類似工程參考。

Abstract:Passenger Terminal Building in Hong Kong-Shenzhen Western Corridor is a super-long mega steel-concrete hybrid structure with complex shape including inclined steel columns, large-span steel girder, and small cross sections. The structure part in Hong Kong needs to meet requirements of relevant codes of both Hong Kong and Mainland of China. There are some difficulties in structural system selection, seismic design, wind resistant design and construction. In design, the seismic joint was arranged in the boundary between Shenzhen and Hong Kong to divide the building into two seismic units, and the reasonable arrangement of the structure was selected. Elastic analysis under frequent earthquake was conducted and the results show that the calculated parameters can meet the requirements of the specifications. The key problems in the seismic analysis and the stability problem of the mega steel structure were analyzed in detail, and the effective measures were taken in the key parts and joints. Accurate wind pressure coefficient and wind vibration coefficient were obtained by wind tunnel test, and wind resistance design was carried out accordingly. The solution to the difficulty of construction was put forward to provide reference for similar engineering.
Keywords:mega steel-concrete hybrid structure; steel box beam; wind tunnel test; stiffness coordination; rigid joint
