The structural analytical model was improved in several different areas.
Use Analytical Model Categories visibility settings to display Local Coordinate System (LCS) widgets along structural analytical elements in a view. The LCS for Columns is now consistent with the LCS for beams and braces. Hosted Loads and Boundary Conditions now can be oriented to the Host LCS. They also respect host LCS direction and rotate as the LCS is changed.
Revit and Revit Structure support the BIM process for structural engineers.
Revit provides a physical model to use for documentation and an associated analytical model to use for structural analysis and design.
An analytical model is a simplified 3D representation of the full engineering description of a structural physical model. The analytical model consists of those structural components, geometry, material properties, and loads, that together form an engineering system. The analytical model is created automatically while you create the physical model, and can be exported to analysis and design applications.
Perform energy analysis using detailed Revit models.
Automatically create an Energy Analytical Model directly from your Revit building elements and send it to Green Building Studio* for simulation using DOE2.2. Once the analysis is complete, you can review and compare results as you continue to iterate the model and help inform your design decisions.
