Research on the Design Method of 3D Parts Library of Prefabricated Concrete Composite Wall-Slab System Based on BIM

Prefabricated buildings are promoting building industrialization and low-carbon development due to their high quality, high efficiency and sustainability. The standardized design process and efficient design method are the fundamental ways to achieve efficient design of prefabricated buildings. In order to solve the problems of low standardization and limited design methods of prefabricated buildings, this study takes the prefabricated concrete composite wall-slab system (PCCWS) as an example and establishes a standardized design process for prefabricated components. Based on the Building Information Model (BIM) technology, a 3D parts library system was established using MATLAB software. The system stores the prefabricated components into the parts library, and the user can search, retrieve, and incorporate them. Taking a prefabricated dormitory project as an example, this study compares the design method of a 3D parts library based on BIM with the traditional design method. The preliminary findings show that the design method proposed in this study can improve the design efficiency by 42.9%. This study has practical significance for improving the design efficiency of prefabricated buildings and reducing production costs and provides a reference for the design method of prefabricated buildings.
