[摘要] 鄂爾多斯機(jī)場(chǎng)新航站樓縱向長(zhǎng)度約500m，下部主體結(jié)構(gòu)采用鋼筋混凝土框架結(jié)構(gòu)，梁中采用了緩粘結(jié)預(yù)應(yīng)力技術(shù)。上部的屋蓋為典型的大跨度空間鋼結(jié)構(gòu)，建筑物中部108m跨的穹頂為采用由24榀徑向桁架和桁架間的單層網(wǎng)殼組成的錐形鋼屋蓋，兩側(cè)登機(jī)廊屋頂均采用網(wǎng)架結(jié)構(gòu)，上部鋼結(jié)構(gòu)和下部混凝土柱的連接節(jié)點(diǎn)采用關(guān)節(jié)軸承支座及“Y”形支撐形式。簡(jiǎn)要介紹了工程的結(jié)構(gòu)設(shè)計(jì)，望能供同類設(shè)計(jì)參考。

Abstract: Ordos new airport building is 500m long, reinforced concrete frame is adopted as low-part structure, retar-bonded post-tensioned prestressed technique is adopted for beams. The roof is a typicallarge-span spatial structure. The central 108m-span dome is built of 24 radial steel tube trusses, and the roof between the steel tube trusses are built of single layer shell. The roof of the boarding gallery on the both side are space grids structure, the roof and the low-part structure are linked by the joint bearing supports and the Y-type columns. This paper gives a brief introduction for the structural design, it can be referred in similar engineerings.
Keywords: retar-bonded post-tensioned prestressed frame structure; Y-type column; bearing support; large-span spatial structure; dome; space grids
