Research On BIM Technology Application And Structural Finite Element Analysis Based On Super High-rise Building

The 21 st century is the age of informatization.Informatization technology has also become the development direction of China's construction industry at the present stage.BIM(Building Information Model),as a digital expression of both physical and functional characteristics of a construction project,is a reliable shared information resource for any decision made during the entire life cycle of a construction project from the initial concept design,and is also a successor to CAD.Afterwards,it promoted another important computer application technology in the information revolution of the construction industry,and with its great value advantages,it promoted the transformation and innovation of the industry concept.With the development of our country's economy and society,the pace of urbanization has been accelerating.The type of buildings with diversified functions,scales,and structures that are represented by super highrise buildings have appeared in people's production and life.The design and construction process of a super high-rise building involves a variety of types of information.There are many technical problems that need to be solved and managed.It is a comprehensive project.How to effectively handle and make full use of this information becomes its design optimization and construction management.A major challenge,at the same time,people have begun to create new needs for the safety of high-rise buildings,and the safety of their structural design has also received increasing attention.This paper introduces the development status of BIM at home and abroad,the concept and three development stages of BIM,the definition of BIM,multidimensional information parameter model,the features of BIM,and the three major supporting IFC,IDM,IFD,promoting BIM high-efficiency information interoperability.The reference AGC classification and Ho's classification method lists the commonly used software related to BIM,the advantages of BIM in the three major objectives of construction projects,and the design of BIM technology in the application of super high-rise buildings in combination with a headquarters building project.At the stage,the problems found in the design of the stairs through the collision check and the integrated design of the pipelines were found through the 3D visualization model,and the net height of certain important parts of the selected layer was developed through the integration of the 3D models of buildings,structures,and electromechanics.Analysis,in the construction phase,using the visual model to demonstrate the three-dimensional construction technology to the workers to make a detailed discussion,making BIM 4D construction simulation with Navisworks.At the same time,this paper also uses the finite element analysis software MIDAS to analyze the safety of the main structure of the headquarters building under the influence of the horizontal load that has a decisive influence on the structural design,through modal analysis to obtain the first twelve natural frequency frequencies and corresponding to the structural vibration characteristics.and obtains the wind load value of each floor through the finite element calculation.The structure's deformation,displacement,displacement angle between layers,wind-induced acceleration,and the maximum stress of the beam element under the most unfavorable load combination are obtained The vibration mode,through the response spectrum analysis to calculate the seismic effect,obtained the design response spectrum curve,structure deformation,displacement,displacement angle between layers,layer shear weight ratio,etc.,and analyzed the above calculation results according to the specifications.
