【摘要】：垂直运输是超高层建筑施工过程中的重点和难点,需要根据工程特点制定合理、高效的垂直运输体系。目前国内外普遍采用的垂直运输方式有塔式起重机、施工电梯、混凝土泵和垃圾通道等。中国建筑第三工程局在香港环球贸易广场项目施工过程中,创造性提出“垂直运输通道塔”的概念,并将其运用到实际工程中,增添了超高层建筑施工过程中垂直运输的方法。天津高银117大厦总高度近600米,属超高层建筑,其施工周期特别紧,难度大,且施工环保要求高。鉴于香港环球贸易广场项目成功的施工经验,中国建筑第三工程局仍决定在这一项目上采用垂直运输塔的施工方案。本文以天津高银117大厦施工垂直运输通道塔为对象,介绍了垂直运输塔钢结构的设计思路和设计成果；通过流体力学软件FLUENT和大型有限元分析设计软件ETABS,在考虑风、温度及地震等不同荷载的前提下,对运输塔进行了分析与验证,得出此种方法的合理性与实用性,为类似超高层建筑施工过程中垂直运输的选择提供很好的参考,并对类似超高层建筑的施工提供了一定的理论指导意义和工程应用价值。本文的主要成果是：提出了垂直运输通道塔钢结构的设计思路和成果,并强调通道塔的设计重点为钢框架节点和附墙杆与主塔结构连接节点两部分。在没有风洞试验数据的情况下,采用流体力学软件FLUENT模拟复杂超高层建筑得到的平均风压和体型系数具有一定的参考价值,且取0°、90°、180°和340。风向对通道塔进行风荷载验算。通道塔设计时,必须建立包含主塔楼的整体分析模型,并考虑天津的温度变化影响。本文一系列的分析成果表明117大厦钢结构通道塔的楼层位移及杆件承载力均满足规范的要求。本文的研究成果为类似项目的垂直运输提供了方便,也为相关的研究提供了有益的依据。
[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 掳to 90 掳. 180 掳and 340 掳. 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.
