Enhanced Rotation Tools in RISA-3D

RISA-3D Version 20 includes enhanced rotation tools which allow the user to better control their view of the structure. Users can now utilize click to rotate buttons about each axis (X, Y and Z) as well as define the rotation angle of each click/increment. For more information about these enhanced rotation tools, check out the video below…

Solving P-Delta Divergences in RISA-3D

In this video, you’ll learn how to investigate your RISA-3D model for P-Delta divergence errors. This type of error is common in general structural analysis software and has two major causes: a model that is unstable or a model that is too flexible. For this investigation, two separate steel frame models will be used to evaluate a workflow to solve P-Delta issues…

How Do I Change the Member Type in RISA-3D?

In RISA-3D, there are many different applications that require you to define Member Type in your model including AISC 15th Edition steel design, Seismic Design, Concrete design, and models that will be transferred to Autodesk Revit. If you find yourself at the end of the project and you forgot to set the member type, here are the steps to easily modify the model. Scenario 1: Section sets were not used. Simply select the member(s) whose type you would like to change, then change the Member Type via the Properties panel on the left hand side. Scenario 2: Section sets were used to build the model. Simply open the Section Sets spreadsheet and change the Member Type as shown below. You can use the Member Color icon to display the Member Type graphically…
