【摘要】：建筑信息模型(Building Information Modeling,BIM)的数据信息能够在建筑的全寿命期中处理、修改、调用、共享和输出的特性,有助于工程师提高决策质量和效率,节约工程项目成本,降低工程风险。我国由于BIM起步较晚,发展相对落后,特别是建筑结构设计阶段,BIM的应用通常以基于传统设计方案的二次建模为主,这种方式不仅增加了结构设计流程和设计成本,而且也限制了BIM在参数化设计方面的优势。为此,本文以某商业综合体为例,基于BIM理念和技术优势,从结构设计人员的角度将BIM应用于结构设计全流程,并基于BIM对抗浮锚杆的优化设计进行应用研究。本文所做工作主要有:(1)梳理国内外BIM相关研究和规范标准,总结传统设计方法存在的弊端和BIM的应用现状及存在的问题。(2)以某商业综合体为工程实例,将BIM应用于实际项目的结构设计中,总结BIM应用设计的基本流程,尝试应用BIM解决实际结构设计中遇到的具体问题和对结构整体性指标进行优化,并将BIM结构结果与传统设计结果进行对比分析。(3)以同一项目的地下室抗浮部分为例,利用BIM技术可视化和模拟性的优势有针对性定点的对抗浮锚杆进行优化设计,并通过有限元分析对BIM模拟结果进行校核。(4)利用BIM的协同优势,给出了建筑方案发生变更时基于BIM的抗浮锚杆设计流程。(5)通过围绕BIM的两部分工程应用实践,从协作方式等三个方面将BIM和传统方法进行对比,总结BIM的优势。
[Abstract]:The data information of Building Information Modeling (BIM) can be processed, modified, called, shared and outputted in the whole life of the building, which is helpful for engineers to improve the quality and efficiency of decision-making, save the cost of engineering projects and reduce engineering risks. Because of the late start of BIM, the development of BIM is relatively backward in our country. Especially, the application of BIM in the stage of building structure design is usually based on the secondary modeling based on the traditional design scheme, which not only increases the structure design process and design cost. It also limits the advantages of BIM in parametric design. Therefore, taking a commercial complex as an example, based on the concept and technical advantages of BIM, BIM is applied to the whole process of structural design from the point of view of structural designers, and the application research is carried out based on the optimization design of BIM anti-floating anchor rod. The main work of this paper is as follows: (1) combing the domestic and foreign BIM related research and standard standards, summarizing the shortcomings of traditional design methods and the application status and existing problems of BIM. (2) taking a commercial complex as an engineering example, This paper applies BIM to the structural design of practical projects, summarizes the basic flow of BIM application design, tries to solve the specific problems encountered in the actual structural design and optimizes the structural integrity index by using BIM. The results of BIM structure and traditional design are compared and analyzed. (3) taking the anti-floating part of the basement of the same project as an example, using the advantages of visualization and simulation of BIM technology, the anti-floating anchor is optimized. The simulation results of BIM are verified by finite element analysis. (4) the design flow of anti-floating anchor based on BIM is given by using the synergistic advantage of BIM. (5) through the two-part engineering application around BIM, the design process of anti-floating anchor rod is given. The advantages of BIM are summarized by comparing BIM with traditional methods from three aspects.
