Description

technical field [0001] The invention relates to the technical field of modular building design and management, in particular to an automatic optimal design method for a modular steel frame building structure based on a building information model (BIM) platform. Background technique [0002] In recent years, in the world, especially in Asia, modular buildings have been vigorously developed and promoted in the field of construction engineering to meet the housing needs and pressure brought about by the growing population, and at the same time solve the existing problems in the traditional building construction process. Problems such as a large amount of resource waste and engineering waste pollution caused by linear construction management. As a type of prefabricated building, factory prefabricated production of structural components can effectively improve the construction efficiency of modular buildings and optimize the configuration of on-site staff. According to the stres...

Problems solved by technology

[0004] The design and digital modeling of the existing modular steel frame building structure are carried out independently. The design process requires manual modification of the design parameters. Every modification requires a verification, and there is no guarantee that the final design is the optimal design. When it is determined Digital modeling is carried out after the final design. In addition, the discussion on the use of BIM is limited to importing the final digital model into the BIM platform. This traditional design mode is complex and time-consuming, and cannot be updated in real time to optimize the design, which is not conducive to Bringing into play the advantages of parallel construction of modular buildings, this technical problem proposes the present invention, the purpose of the present invention is to solve the technical problems of the application of the above-mentioned existing building information modeling technology in the design of modular building structures, in the building information modeling platform (BIM ) realizes the automatic optimal design of modular steel frame building structures, ensures that the design responds to changes in project information in real time, automatically determines the optimal design scheme, and facilitates timely coordination of work arrangements for project participants
