【摘要】：垂直運輸是超高層建筑施工過程中的重點和難點,需要根據(jù)工程特點制定合理、高效的垂直運輸體系。目前國內(nèi)外普遍采用的垂直運輸方式有塔式起重機、施工電梯、混凝土泵和垃圾通道等。中國建筑第三工程局在香港環(huán)球貿(mào)易廣場項目施工過程中,創(chuàng)造性提出“垂直運輸通道塔”的概念,并將其運用到實際工程中,增添了超高層建筑施工過程中垂直運輸?shù)姆椒ā?天津高銀117大廈總高度近600米,屬超高層建筑,其施工周期特別緊,難度大,且施工環(huán)保要求高。鑒于香港環(huán)球貿(mào)易廣場項目成功的施工經(jīng)驗,中國建筑第三工程局仍決定在這一項目上采用垂直運輸塔的施工方案。 本文以天津高銀117大廈施工垂直運輸通道塔為對象,介紹了垂直運輸塔鋼結(jié)構(gòu)的設(shè)計思路和設(shè)計成果；通過流體力學(xué)軟件FLUENT和大型有限元分析設(shè)計軟件ETABS,在考慮風(fēng)、溫度及地震等不同荷載的前提下,對運輸塔進行了分析與驗證,得出此種方法的合理性與實用性,為類似超高層建筑施工過程中垂直運輸?shù)倪x擇提供很好的參考,并對類似超高層建筑的施工提供了一定的理論指導(dǎo)意義和工程應(yīng)用價值。 本文的主要成果是：提出了垂直運輸通道塔鋼結(jié)構(gòu)的設(shè)計思路和成果,并強調(diào)通道塔的設(shè)計重點為鋼框架節(jié)點和附墻桿與主塔結(jié)構(gòu)連接節(jié)點兩部分。在沒有風(fēng)洞試驗數(shù)據(jù)的情況下,采用流體力學(xué)軟件FLUENT模擬復(fù)雜超高層建筑得到的平均風(fēng)壓和體型系數(shù)具有一定的參考價值,且取0°、90°、180°和340。風(fēng)向?qū)νǖ浪M行風(fēng)荷載驗算。通道塔設(shè)計時,必須建立包含主塔樓的整體分析模型,并考慮天津的溫度變化影響。本文一系列的分析成果表明117大廈鋼結(jié)構(gòu)通道塔的樓層位移及桿件承載力均滿足規(guī)范的要求。 本文的研究成果為類似項目的垂直運輸提供了方便,也為相關(guān)的研究提供了有益的依據(jù)。
[Abstract]:Vertical transportation is an important and difficult point in the construction of super high-rise building. It is necessary to establish a reasonable and efficient vertical transportation system according to the characteristics of the project. At present, tower crane is widely used in vertical transportation at home and abroad. Construction elevator, concrete pump and garbage passage etc. During the construction of Hong Kong Global Trade Plaza Project, the third Engineering Bureau of China Building creatively put forward the concept of "vertical transport corridor tower". The method of vertical transportation in the construction process of super-tall building is added to the practical engineering. Tianjin Gaoyin 117 Building, with a total height of nearly 600 meters, is a super high-rise building with a very tight construction cycle and a high level of environmental protection. In view of the successful construction experience of the Hong Kong Global Trade Square Project. China Construction third Engineering Bureau still decided to use the vertical transport tower construction plan for the project. In this paper, the design ideas and results of the steel structure of the vertical transport tower are introduced with the construction of the vertical transport corridor tower of Gaoyin 117 Building in Tianjin as the object. Through the fluid mechanics software FLUENT and the large-scale finite element analysis and design software ETABS, under the premise of considering the different loads such as wind, temperature and earthquake, the analysis and verification of the transport tower are carried out. The rationality and practicability of this method are obtained, which provides a good reference for the selection of vertical transportation in the construction process of similar super high-rise buildings. It also provides some theoretical guidance and engineering application value for the construction of similar super-high-rise buildings. The main achievements of this paper are as follows: the design idea and achievement of the steel structure of vertical transportation passage tower are put forward. It is emphasized that the design emphasis of the passage tower is the steel frame joint and the connection joint between the wall rod and the main tower structure, without wind tunnel test data. Using the fluid mechanics software FLUENT to simulate the average wind pressure and body shape coefficient of complex super-tall buildings has certain reference value, and takes 0 擄to 90 擄. 180 擄and 340 擄. Wind direction is used to check the wind load on the passage tower. In the design of the passage tower, an overall analysis model including the main tower must be established. A series of analysis results show that the floor displacement and the bearing capacity of the steel trunking tower of 117 Tower meet the requirements of the code. The research results of this paper provide convenience for the vertical transportation of similar projects, and also provide a useful basis for the relevant research.
