Reinforced Concrete Building - Seismic Analysis and Shear Design (BIM Workflow)¶
Introduction¶
Welcome to the Seismic Analysis and Shear Design (BIM Workflow) tutorial.
In this course we are investigating the seismic behaviour of a highrise building modelled in Revit using SOFiSTiK Analysis + Design and the SOFiSTiK Structural Desktop.
By the end of the tutorial, you should be able to:
Prepare a Revit model for a seismic project and generate a corresponding Finite Element model.
Conduct a seismic Response Spectrum Analysis (RSA) for this model.
Perform designs and checks of structural elements for horizontal bracing (i.e. shear walls and building cores).
Evaluate results of these seismic analyses and designs in the BIM model.
Before you start, please make sure you have the following software products installed: Revit Analysis + Design SSD installed.
If you have technical difficulties, please reach out to our SOFiSTiK Technical Support.
Let’s get started!

Preparation of the model in Revit¶
Storey Levels¶
Define which Revit levels you would like to use as SOFiSTiK Storey Level in the analysis.
Shear Walls¶
Determine which structural walls of the Revit model are participating to the horizontal bracing of the structure and should be designed as shear walls.
Building Cores and its Shear Walls¶
Add building cores to the model, linking shear walls groups across levels in a single analytical object.
Tip
It is possible to save results in the Revit Project via the Save as Package dialog. Supported results include:
Forces from the building core elements
Required reinforcement for the shear walls
Results stored in a Revit results package can be visualized in Show Results by changing the data base to the results package. For more info, see the respective SOFiSTiK Analysis + Design documentation.
Analysis¶
Earthquake RSA - reloaded¶
Perform the response spectrum analysis by using the Earthquake RSA reloaded Task.
Storey Checks¶
Proceed with the superpositioning and storey checks.
Design¶
Shear Wall Design¶
Perform the shear wall design with a Simplified Compression & Tension Method. The design is based on the integrated forces of the individual walls.
Capacity Check¶
Conduct the capacity check for the building core. The check is based on the integrated forces of all walls associated with a core and its specific reinforcement layout.
