Abstract: A Building Information Modeling (BIM)-based intelligent drafting method for prefabricated buildings includes the following steps: step 1: extracting building model information; step 2: modeling the building model information, where Revit elements are divided into model elements, datum elements, and view-specific elements; step 3: extracting element management information based on a BIM model; step 4: extracting a sub-model view based on a BIM global model; step 5: performing BIM-based three-dimensional (3D) parametric modeling; and step 6: performing intelligent drafting for the prefabricated buildings: extracting structure information by an integrated platform for production, sales, and construction of the prefabricated buildings, extracting architectural, structural and mechanical electrical BIM models and generating drawings with a quick response (QR) code.

Abstract: A method for determining an optimal arrangement of circular pipe supports of a steel silo composite shear wall, including: designing a set of steel silo composite shear wall model including parameters of interval of the circular pipe supports, axial-load ratio, steel ratio and aspect ratio: establishing an ABAQUS finite element model including initial defect; performing force analysis by the finite element software ABAQUS and calculating a horizontal ultimate bearing capacity; fitting formulas of the horizontal ultimate bearing capacity of the steel silo composite shear wall by applying least square method; drawing a relationship curve between the interval of the circular pipe supports and the horizontal ultimate bearing capacity; determining the optimal arrangement of the circular pipe supports of the steel silo composite shear wall according to a critical point of the relationship curve between the interval of the circular pipe supports and the horizontal ultimate bearing capacity.
