The most simple, efficient and fast way to analyze structural walls and columns to lateral forces (seismic loads , wind loads) in non linear analysis is by combining the features of the following softwares: Robot Structural Analysis, Revit Structure and Altiscad Intellishape.  The use of extensions helps the user in the integration process.
 
Autodesk provides their customers with a series of extensions necessary for the integration and detailing process. For this process to be completed,  Altiscad Intellishape Extension completes the integration between the three programs.

 

The benefit of the integration is the iterative procedure and its steps:

1. Using Robot Structural Analysis (ex Robot Millennium) the   model of the structure is made (geometrical model, loads, seismic parameters, combinations etc) and then the same software proceeds with the design anlysis.
2. The structural model is then transferred from Robot to Revit using Revit's extensions. These are available with the Autodesk subscription.
3. The reinforcement of the concrete elements is the realized using Revit's special tools.
4. Using  Altiscad Intellishape Extension the reinforced concrete elements are transferred to  Altiscad Intellishape. The extension allows the transfer of the reinforced cross section with materials from Revit, but also the import of forces from    Robot Structural Analysis (from all combinations to the selected element). 
5. The section is then analized and the moment curvature diagrams are provided: N-M, Mx-My and the geometrical characteristics of the cross section. The forces are then verified by observing their placement in the interior or in the exterior of the diagram. There are also other coefficients available like the compression ratio of the section.
6. For the next step, we modify the geometric characteristics in Robot Structural Analysis (reduced moments of inertia due to the cracking of the section).
7. The iterative process is then replayed from step 1 to step 5 until all the requirements are fulfilled.
8. The reinforced elements are then transferred from Autodesk Revit Structure to ASD.
9. In the last step, the final execution drawings are made in Autodesk Autocad Structural Detailing.
