VIDEO: Creating Custom Shapes in RISA-3D
Learn how to build custom steel and concrete shapes using RISASection and then import them into RISA-3D to incorporate them in analysis and design.
RISACalc in the Field: A Case Study in Confidence and Convenience It was a typical Thursday morning for Emma Ruiz, PE, a structural engineer at a small consulting firm in Colorado. Her day started with a site visit to a rural school renovation—a project where her team was assessing whether a portion of the existing structure could support new rooftop HVAC units. The original framing plans were incomplete, and as Emma inspected the roof framing, it became clear that the contractor’s proposed unit placement didn’t line up with the assumed beam layout. A decision had to be made, and quickly—the rooftop unit was scheduled for delivery the following day. The Problem: Time-Sensitive Field Check Emma didn’t have time to return to the office to rebuild a full model or dig through spreadsheets for older framing checks. She needed to verify—on the spot—whether the existing W10x22 steel beam could support the new loads at the proposed spacing. The contractor waited, the facilities director asked for reassurance, and Emma pulled out her tablet. The Solution: RISACalc in Action Emma opened RISACalc, selected the beam design template, and input the beam size, span length, and newly calculated roof loads, including snow and equipment…

When using RISA Integration between RISASection and RISA-3D, RISA-2D and/or RISAFloor, there are a few common mistakes that people make when attempting to access the RISASection files from the Shape Database.
There are multiple options in RISA-3D and RISAFloor to create a custom shape not available in the program databases. The first, is to utilize RISASection in order to create cross-sections, calculate section properties and import the shape directly into RISA-3D. For more information on integrating...
Use RISASection to find the properties of built-up steel sections, then model beams using the same section properties in RISA-3D and get full code-checks using AISC 360. This webinar will teach you how to use RISASection quickly and easily to determine complex section properties.
RISASection v2 includes updated torsional shape properties for a more accurate analysis. Check out the video below for more information:
In order to get code calculations, RISA-3D and RISA-2D need to know what type of shape would be most similar to yours. This is because the program needs to use the correct code equations for your shape type.
RISASection 2.0 includes the ability to assign your section as one of the predefined hot rolled steel Shape Types (Wide Flange, Channel, Tube, etc.). This means that when the shape is imported into RISA-3D, you will now be able to get design results and code checks for the member.
The latest version of RISASection, includes a powerful new DXF import feature. This feature allows the user to import any 2D geometry into RISASection for the calculation of the cross-sectional properties and the import into RISA-2D, RISA-3D or RISAFloor for use in the larger model.
Modeling built-up or composite sections can easily be done in RISASection. Because the properties of such a section are computed using a weighted summation of the transformed shape properties, RISASection uses a Property Multiplier to specify the relative weight of a single shape in a built up...
