The core of the Open BIM concept is the exchange of reference models between various disciplines.
The structural engineer communicates with designers via structural models; these are 3D as-built representations of the structure. He will use this information as a reference (the reference model) to create the analysis model, consisting mainly of 1D- and 2D-elements connecting at the analytical nodes.
Instead of modeling from scratch, today's powerful Open BIM tools make it possible to speed up this process by re-using the information of the reference model. Not connected elements are aligned, reference objects are transformed to equivalent analysis objects and subsequent changes in the reference model are propagated in a controlled manner to the engineer’s analysis model.
Open BIM workflow for the analysis of structural models
Import the structural model as a reference model
Convert (a part of) the structural model to an analysis model
Perform the Analysis and Design and change the design accordingly
Export the structural model to collaborate and coordinate
Extension to the coordination of the design and analysis
Import changes in the structural model
Compare to the existing analysis model
Accept, decline or ignore changes
Export changes in the analysis and structural model to collaborate and coordinate
Open BIM workflow for Structural Engineers: From the Architectural model to a reference model to create the analysis model
Open BIM with SCIA Engineer
SCIA Engineer is the only Structural Analysis software that fully supports the Open BIM concept thanks to its dedicated BIM tools for the structural engineer:
IFC is the international, fully stable and non-proprietary standard for exchanging BIM data and makes Open BIM possible. SCIA Engineer is the only CAE analysis software that is IFC 2x3 certified by buildingSMART and fully supports the implementation of the Coordination View 2.0.
Smart shape-recognition algorithms make it possible to convert any structural object, both simple and complex, to equivalent analytical members. Fast and easy recognition of the geometry, cross section and material.
Scia Engineer can recognize solids and convert them into members which can be used for calculation
Revision and coordination is an important part of the Open BIM workflow. In order to manage the changes as an Engineer, a tool to compare projects is essential. Model Update gives you more power and better insight over the changes that occurred and the ability to accept or deny them
Compare models to see what has been changed because of revision with a clear color coding
Gain time by applying the changes to the current analysis model instead of remodeling
Keep control over the analysis model by accepting only relevant changes because of revision without the loss of earlier work
Accept changes in the project to keep control over revisions in the analysis model
