The embodiment of the application provides a kind of bridge BIM model to bridge FEM model conversion method, it is related to bridge design technical field, method includes: from bridge BIM model, export IFC data to extract the cross-sectional characteristics of bridge component, and then determine cross-sectional geometric parameters;Again, the cross-sectional geometric parameters of mutually different cross-sections are stored as component information files, and the geometric parameters of mutually different cross-sections are stored as cross-sectional information files;Based on component information file, connection relationship file for storing the connection relationship of adjacent bridge components is constructed, boundary condition file for storing the boundary information of bridge as a whole and node information file for storing the centroid point coordinates of bridge component, finally, these JSON file formats are converted into the format file of bridge FEM model.The application is used to solve the problem that BIM model and FEM model need to be modeled separately in the process of bridge design, the model cannot be reused, resulting in low efficiency of bridge design.

This invention relates to the field of prestressed hollow core slab design. Currently, the process design for hollow core slab systems is unclear. This invention proposes a BIM-based prestressed hollow core slab design method, comprising: establishing a BIM model of the framework; providing a prestressed hollow core slab BIM database to the designer; determining the design load values ​​for the spans, the thickness of the prestressed hollow core slabs, and the initial layout direction; determining the slab direction layout and reinforcement for each span; determining the final simply supported layout diagram of the prestressed hollow core slabs and ensuring the accuracy of the layout; determining the locations of water and electricity pipes for the hollow core slabs and the locations of openings below the slab holes; outputting overall project information data reports; generating production processing tables for each production line; outputting the production processing tables to the factory for standardized assembly line production; generating QR codes through input into the production management system; and on-site construction and installation. This method improves production efficiency, achieves seamless integration from design to production and construction, and enables precise construction, demonstrating promising development prospects in the field of prestressed hollow core slab design.
