【摘要】 改革开放以来,我国建筑业快速发展,高层建筑也随着城镇化进程的加快,在建设工程中越来越常见,高层建筑与一般低层建筑相比,建筑规模大、结构复杂、功能多样,给项目精益建造带来巨大挑战,利用传统的CAD蓝图指导施工不足以解决施工现场的各类问题。本文以某金融中心大厦项目为例,探讨BIM(建筑信息模型)技术在项目设计与施工阶段的应用,利用相关BIM软件建立专业三维模型,深入研究BIM在设计与施工阶段的应用方式。主要内容如下:(1)对市场上主流的4款BIM软件进行对比,选择一款合适的软件作为金融中心大厦项目的建模与施工仿真工具;(2)针对金融中心大厦项目的特点,对项目各阶段制定具体的BIM实施目标,组建BIM团队,介绍建模流程;(3)针对金融中心大厦项目施工阶段,细化建筑、结构、机电、幕墙等专业模型,利用三维模型对项目进行碰撞检查,根据碰撞检查结果修改设计,为现场施工提供指导;(4)基于BIM技术的优势,在BIM施工仿真平台上对结构施工过程的总体施工设计、施工方案模拟、进度管理、成本控制进行应用研究。(5)重点在于运用建筑信息模型(BIM)技术和有限元分析来确保钢结构的安全性。首先,需确定钢结构的材料特性和截面参数,并通过软件接口将Revit设计的钢结构模型传输至Midas Gen中。详细说明作用在结构上的各类荷载、设置边界条件,并参考相关的计算标准。通过有限元分析执行静态评估,检查各构件的应力与变形;同时进行动态分析,确定结构的前十阶固有频率及其振动形态,并利用反应谱分析来考察结构在地震作用下的应力与位移表现,根据现行规范对所得结果进行评估。更多还原

【Abstract】 Since the reform and opening up,the construction industry in China has developed rapidly,and high-rise buildings have become increasingly common in construction projects as the urbanization process accelerates.Compared with low-rise buildings,high-rise buildings have larger scale,more complex structures,and diverse functions,which bring huge challenges to lean construction.Using traditional CAD drawings to guide construction on site is not enough to solve various problems on the construction site.This paper takes the Financial Center Building project as an example to explore the application of BIM(Building Information Modeling)technology in the design and construction stages of a project.Using relevant BIM software to establish professional3D models,the paper studies the application modes of BIM in the design and construction stages in depth.The main contents are as follows:(1)Four mainstream BIM software on the market were selected and compared,and one suitable software was chosen as the model building and construction simulation tool for the financial center building project;(2)Based on the characteristics of the financial center building project,specific BIM implementation objectives were set for each stage of the project,a BIM team was formed,and the modeling process was introduced;(3)For the construction stage of the financial center building project,the professional models of architecture,structure,mechanical and electrical,and curtain wall were refined,and the project was collision-checked using the three-dimensional model.The design was revised according to the check results,and some guidance was provided for the site construction;(4)Based on the advantages of BIM technology,the overall construction design,working scheme simulation,schedule management,and cost control of the structural construction process were applied and studied on the BIM construction simulation platform.(5)The focus is on utilizing Building Information Modeling(BIM)technology and finite element analysis to ensure the safety of steel structures.Firstly,it is necessary to define the material properties and cross-sectional parameters of the steel structure,and transfer the Revit-designed steel structure model via a software interface into Midas Gen.Detailed descriptions of various loads acting on the structure,setting boundary conditions,and referencing relevant calculation standards should be provided.Static evaluations are then conducted through finite element analysis to inspect the stress and deformation of each component;concurrently,dynamic analyses are performed to determine the first ten natural frequencies and their corresponding vibration modes of the structure.Seismic stress and displacement responses are evaluated using response spectrum analysis,and the results are assessed according to current standards.更多还原
