Automating stability analysis using BIM-FEA-Integration
Automating stability analysis using BIM-FEA-Integration
This paper examines chances and frontiers of BIM-to-FEA integration for geotechnical projects using a real-world excavation pit project underscoring its practical applicability. A BIM model is first created, which includes the urban context, the subsoil, the excavation pit, and the building to be erected. Elements relevant to the numerical model are identified, pre-processed and transferred to the FEA software leveraging an interactive automation routine. After the calculations and stability analysis, the results are back-transferred to the BIM model, which triggers an update routine for geometries and properties of the BIM model’s objects enabled by their parametric definition. It is demonstrated that 2D numerical models can be derived from a complex BIM model. Strict adherence to the model structure and the establishment of appropriate modelling rules are prerequisites for this. The approach allows real-time interaction between BIM and FEA with automatic compliance of the stability. The developed automation process shows potential for efficiency gains, particularly in variational analyses and supports version control and data consistency.
