Structure Design Method Based On BIM Technology Research

BIM technology is causing the advent of "information technology" revolution in the engineering construction industry,BIM technology is the core of the construction project whole life cycle of data information and resource sharing,committed to the solution by means of digital and information-based construction industry production low efficiency,severe resource waste,and the type of work between the problem such as "information fault",to realize the cooperative work between different stages and different specialties in construction projects";in recent years,with the localization of BIM software and mature of the secondary development environment,domestic engineering construction industry whole life cycle of the BIM technology application to explore research,According to the survey,at present,the domestic architectural design,construction equipment and construction stage of BIM technology has been applied in some large projects,the structure of professional acceptance and application of BIM technology is far less than the depth and breadth of construction,construction equipment and other professional,this seriously hindered the construction project life cycle of BIM technology popularization and application,Therefore,the research on the application of BIM technology in structural specialty has practical value and practical significance.In order to realize the application of BIM technology,this paper studies the structural design method based on BIM technology,which mainly includes the following four aspects:(1)Based on the analysis of the traditional design method,put forward from the traditional to the BIM collaborative design based on the design pattern of the transition,and gives specific method,namely from "professional cooperation" to "coordinated" local to global transition method,at the same time,this paper gives the specific cooperation process of the two kinds of collaborative design,and gives the structural design flow based on BIM technology,for the realization of the whole design phase of the "stage of cooperation" and even the construction of the project life cycle of BIM technology to lay a solid foundation.(2)Combined with the engineering case,the BIM technology application platform software Revit and structural analysis software ETABS are used to verify the bidirectional link and According to connection,such as the loss of data information,in the process of information error is not problem using Revit provide Application programming Interface(API(Application Programing Interface)Revit software for secondary development,in order to extract the required structural information,which can be used to supplement and improve the data information,and to realize the seamless link between the BIM application platform and the structural calculation software information.(3)The secondary development of Revit and structural analysis software ETABS program,realized the structural design method based on BIM technology.first of all,the structural analysis and calculation are carried out for the actual engineering cases,and the structural members are designed according to the calculation results in ETABS,finally,update the design information to the Revit platform to adjust and modify the structure model.(4)For the BIM technology construction drawing expression of regional defects,the paper proposed a method of BIM and flat method fusion to give full play to the advantages of both.first of all,the feasibility of the fusion is analyzed,and the two methods are proved by creating "shared parameters" and "project parameters",the results show that it is effective to achieve the integration of BIM and flat method by creating "shared parameters" and "project parameters",but it is often necessary to use the two methods in the project,in the end,the paper gives the concrete working process of the two methods,and realizes the entity reinforcement based on BIM technology in Revit.
