【摘要】：建筑信息化模型(BIM,Buliding Information Modeling)是一種全新的建模理念和技術(shù),已滲入國內(nèi)外建設項目的設計、施工、成本核算等階段中,為項目創(chuàng)造價值。然而利用BIM技術(shù)處理大型項目的細節(jié)問題,如復雜節(jié)點鋼筋排布、鋼結(jié)構(gòu)構(gòu)件連接、多專業(yè)施工配合等內(nèi)容的研究并不多。本文將結(jié)合復雜節(jié)點在施工技術(shù)中的問題,應用三維深化設計軟件對型鋼混凝土結(jié)構(gòu)的復雜節(jié)點進行三維模型分析和施工模擬分析,提前解決施工中存在的典型問題。復雜節(jié)點往往鋼筋排布密集、構(gòu)造異形、施工困難,無論是在深化設計階段還是在施工階段都存在許多問題,屬于設計和施工中的需要特別強調(diào)的部位,本文通過研究一個實際案例的節(jié)點深化設計,提前解決設計、施工中的問題,并總結(jié)出利用BIM技術(shù)進行復雜節(jié)點深化設計的技術(shù)方法及思路。本文的主要研究內(nèi)容及成果如下:(1)利用合理的BIM軟件建立復雜節(jié)點中各專業(yè)的模型,通過IFC標準的轉(zhuǎn)換格式合并各專業(yè)模型并做修正,形成可用于指導施工的BIM模型。結(jié)合模型和施工現(xiàn)場,分析得出復雜節(jié)點中需要深化設計的重點問題和重點構(gòu)件。(2)利用BIM技術(shù)完成具體工程復雜節(jié)點的深化設計,將施工中可能遇見的問題分類并提出解決措施,實現(xiàn)虛擬施工和實際施工的完全對接。對該節(jié)點的深化設計過程進行由特殊到一般的總結(jié)歸納,得出復雜節(jié)點深化設計的通用流程和技術(shù)措施。(3)研究節(jié)點連接板處增加加勁肋板的合理性,將BIM節(jié)點模型簡化并導入有限元分析軟件Abaqus中,對三種加勁肋加設方式進行受力分析,對比分析計算結(jié)果后,選擇最優(yōu)的加勁肋設計方案應用于施工現(xiàn)場。(4)從經(jīng)濟性角度分析BIM技術(shù)在復雜節(jié)點深化設計中的可行性。建立了BIM投資回報率測算模型,通過此模型估算案例工程項目中轉(zhuǎn)換層應用BIM技術(shù)后的投資回報率。通過評估可知,精準出圖、減少工程變更、減少施工碰撞是施工企業(yè)投資BIM的最大動力,且BIM技術(shù)能夠為項目帶來較好的經(jīng)濟收益。
[Abstract]:Building information model (BIM,Buliding Information Modeling) is a new modeling concept and technology, which has penetrated into the design, construction, cost accounting and other stages of construction projects at home and abroad to create value for the project. However, using BIM technology to deal with the details of large-scale projects, such as the layout of complex joint reinforcement, steel structural member connection, multi-professional construction coordination and so on is not much research. In this paper, combined with the problems of complex joints in construction technology, 3D model analysis and construction simulation analysis of complex joints of steel reinforced concrete structures are carried out by using 3D deepening design software to solve the typical problems in construction ahead of time. Complex joints are often reinforced with dense arrangement, irregular structures and difficult construction. There are many problems in both the deepening design and construction stages, which belong to the parts that need special emphasis in design and construction. In this paper, the problems in design and construction are solved in advance by studying the nodal deepening design of a practical case, and the technical methods and ideas of using BIM technology to deepen the design of complex nodes are summarized. The main contents and achievements of this paper are as follows: (1) using reasonable BIM software to establish the model of each specialty in complex nodes, combining and modifying the specialized models through the conversion format of IFC standard, forming the BIM model which can be used to guide the construction. Combined with the model and construction site, the key problems and key components needed to deepen the design of complex nodes are analyzed. (2) using BIM technology to complete the deepening design of complex nodes in specific projects, The possible problems in construction are classified and the solving measures are put forward to realize the complete docking between virtual construction and actual construction. The deepening design process of the joint is summarized from special to general, and the general process and technical measures for deepening the design of complex joint are obtained. (3) the rationality of adding stiffened ribbed slab at the joint connection plate is studied. The BIM node model is simplified and imported into the finite element analysis software Abaqus to analyze the stress of the three stiffeners, and the results are compared and calculated. The optimal stiffener design scheme is selected to be applied to the construction site. (4) the feasibility of BIM technology in the design of complex joints is analyzed from the economic point of view. In this paper, the model of BIM investment rate of return is established. The model is used to estimate the rate of return of investment after the application of BIM technology in the conversion layer of a case engineering project. Through evaluation, we can see that accurate drawing, reducing engineering changes and reducing construction collision is the biggest power for construction enterprises to invest in BIM, and BIM technology can bring better economic benefits for the project.
