Abstract: Conventional concentrated line-load assessment based on beam cross-sectional parameters may neglect additional loads from adjacent walls, slabs, and architectural feature elements during construction, leading to missed identification of some high-load beams. To address this problem and improve the efficiency of control-parameter screening and support-frame modeling, this study proposes a BIM-based framework for high-risk concrete formwork support system design considering multi-component load coupling. Using the structural BIM model as the data source, the framework classifies loading conditions according to the spatial topological relationships between beams and associated components, and obtains corrected concentrated line loads by calculating the effective additional volume and applying an equivalent-height correction. On this basis, control parameters are automatically screened following a “safety classification–economic partitioning–interval output” procedure, and support-frame models are parametrically generated using a “line–solid separation” strategy. The framework was validated through a case study of a basement project in Jiangxi Province, China. Among 210 beams, 27 high-load beams were identified, including seven involving wall–slab coupling, five of which were missed by the conventional cross-section-based method. For these seven beams, the maximum and mean absolute percentage errors between the corrected concentrated line loads and the manually calculated reference values were 4.23% and 2.46%, respectively. Compared with the conventional method, the total design time was reduced from 115 min to 5.11 min, representing a reduction of 95.6%. The proposed framework can reduce the risk of missing high-load beams under complex structural conditions while improving the efficiency and reliability of high-risk concrete formwork support design.
