【摘要】：建筑信息化模型(BIM,Buliding Information Modeling)是一种全新的建模理念和技术,已渗入国内外建设项目的设计、施工、成本核算等阶段中,为项目创造价值。然而利用BIM技术处理大型项目的细节问题,如复杂节点钢筋排布、钢结构构件连接、多专业施工配合等内容的研究并不多。本文将结合复杂节点在施工技术中的问题,应用三维深化设计软件对型钢混凝土结构的复杂节点进行三维模型分析和施工模拟分析,提前解决施工中存在的典型问题。复杂节点往往钢筋排布密集、构造异形、施工困难,无论是在深化设计阶段还是在施工阶段都存在许多问题,属于设计和施工中的需要特别强调的部位,本文通过研究一个实际案例的节点深化设计,提前解决设计、施工中的问题,并总结出利用BIM技术进行复杂节点深化设计的技术方法及思路。本文的主要研究内容及成果如下:(1)利用合理的BIM软件建立复杂节点中各专业的模型,通过IFC标准的转换格式合并各专业模型并做修正,形成可用于指导施工的BIM模型。结合模型和施工现场,分析得出复杂节点中需要深化设计的重点问题和重点构件。(2)利用BIM技术完成具体工程复杂节点的深化设计,将施工中可能遇见的问题分类并提出解决措施,实现虚拟施工和实际施工的完全对接。对该节点的深化设计过程进行由特殊到一般的总结归纳,得出复杂节点深化设计的通用流程和技术措施。(3)研究节点连接板处增加加劲肋板的合理性,将BIM节点模型简化并导入有限元分析软件Abaqus中,对三种加劲肋加设方式进行受力分析,对比分析计算结果后,选择最优的加劲肋设计方案应用于施工现场。(4)从经济性角度分析BIM技术在复杂节点深化设计中的可行性。建立了BIM投资回报率测算模型,通过此模型估算案例工程项目中转换层应用BIM技术后的投资回报率。通过评估可知,精准出图、减少工程变更、减少施工碰撞是施工企业投资BIM的最大动力,且BIM技术能够为项目带来较好的经济收益。
[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.
