【摘要】：建筑信息模型是应信息化技术快速发展的背景而产生的一种针对于建筑业的信息化成果,BIM是一种技术,同时也是一种理念,它颠覆了传统的建筑行业对于建筑设计及交互运作的理念,贯穿于包括规划设计,施工建造,竣工交付,后期运营的全生命周期。结构专业在BIM实施的过程中一直处于一种很尴尬的境地,这是由于结构专业在分析模型方面的特殊性,Revit软件本身并不能对建筑结构做出准确的分析,所以一般需要结合专业的结构分析软件来配合使用。地震灾害逐年发生,给人类带来的损失惨重,而对地震灾害有了更为深刻的认知,与之相对应的是建筑领域的抗震设计水平逐步得到了提升,新的建筑结构也采取了更为有效、更为稳妥的抗震设计与构造措施来降低地震对建筑物的损害。对于不满足抗震设防要求的既有建筑,拆除重建会造成一定得环境污染与资源浪费,所以对既有建筑的加固改造成为主要的解决办法。传统的加固方式对建筑周围环境与居民的生活有较大影响,一般需要入户施工,且施工周期较长,对居民的周转安置问题较难解决。本文的依托于Autodesk Revit平台,针对北京市建筑设计研究院自主研发的结构分析软件PACO及其提出的既有建筑装配式外套加固技术,进行基于BIM的装配式加固设计模型的研究,主要研究内容如下:(1)综合分析利用MIDAS以及SAP2000分析砌体结构外套加固设计模型的应用限制以及缺陷,提出PACO分析软件的优势以及必要性;(2)基于REVIT平台以及装配式外套加固体系开发一套相应的外套加固族库,达到参数化设计以及自适应构件的标准;(3)基于Visual Studio C#编程语言,对结构分析软件PACO与Autodesk Revit进行接口开发,实现PACO软件的分析模型到Autodesk Revit物理模型的转换;(4)依托实际工程甘家口住宅小区1#楼,进行加固设计分析,导出数据,通过开发的接口以及开发的装配式外套加固族库,进行从PACO结构分析模型到Autodesk Revit物理模型的转换,进而验证研究成果。结果表明,通过建立成套Revit加固族库,可以更快的建立加固设计的BIM模型;通过对Revit二次开发,编译程序调用参数驱动建模可以快速将结构分析模型转换为Revit模型,后期可以通过Revit软件自身的优势进行快速出图以及后期项目管理。
[Abstract]:Building information model is a kind of information achievement aiming at the construction industry. BIM is not only a technology, but also a kind of idea, which comes from the background of the rapid development of information technology. It overturns the traditional architecture industry's concept of architectural design and interactive operation, and runs through the whole life cycle, including planning and design, construction and construction, completion and delivery, and later operation. The specialty of structure has always been in a very awkward position in the process of implementing BIM. This is because the particularity of structural specialty in analyzing model can not make an accurate analysis of the building structure. So generally need to combine professional structure analysis software to cooperate with the use. Earthquake disasters occur year by year, causing heavy losses to human beings, but they have a deeper understanding of earthquake disasters, corresponding to the gradual improvement of the level of seismic design in the field of building, and the new building structure has also been adopted more effectively. More reliable seismic design and structural measures to reduce earthquake damage to buildings. For the existing buildings which do not meet the requirements of seismic fortification demolition and reconstruction will cause certain environmental pollution and waste of resources so the reinforcement and transformation of the existing buildings become the main solution. The traditional reinforcement method has great influence on the surrounding environment of the building and the life of the residents. Generally, it is necessary to enter the house for construction, and the construction period is longer, so it is difficult to solve the problem of the residents' turnaround placement. In this paper, based on Autodesk Revit platform, the structure analysis software PACO developed by Beijing Institute of Architectural Design and Research Institute and its existing building assembly coat reinforcement technology are studied. The model of assembly reinforcement design based on BIM is studied. The main research contents are as follows: (1) the limitations and defects of the design model of masonry structure jacket reinforcement are analyzed by MIDAS and SAP2000. The advantages and necessity of PACO analysis software are put forward. (2) based on REVIT platform and assembly jacket reinforcement system, a set of corresponding jacket reinforcement family library is developed to meet the standard of parameterized design and adaptive component. (3) based on Visual Studio C # programming language, The interface between PACO and Autodesk Revit is developed to realize the conversion from PACO software analysis model to Autodesk Revit physical model. (4) based on the actual project of Ganjiakou residential district 1# building, the reinforcement design analysis is carried out, and the data are derived. Through the interface developed and the fabricated jacket strengthened family library, the transformation from PACO structure analysis model to Autodesk Revit physical model is carried out, and the research results are verified. The results show that the BIM model of reinforcement design can be established more quickly by establishing a complete set of Revit reinforcement family library, and the structural analysis model can be quickly transformed into Revit model by the second development of Revit. In the later stage, the Revit software can be used for quick drawing and project management.
