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.
The 4th of July is a time for celebration, fireworks, and, of course, a bit of fun. For those with a knack for engineering or simply looking to engage in some creative activities, why not take on some patriotic engineering challenges? These activities are perfect for kids and adults alike, providing an entertaining way to celebrate Independence Day while sharpening your problem-solving skills. Here are three exciting challenges to get you started: 1. Popsicle Stick Bridge Materials Needed: Popsicle sticks Glue (wood glue or a hot glue gun) Small weights (coins, toy cars, etc.) Challenge: Design and build a small bridge using only popsicle sticks and glue. The goal is to create a bridge that can support as much weight as possible. This activity not only tests your creativity but also your understanding of structural integrity and load distribution. Instructions: Plan Your Design: Before you start gluing, sketch out a design for your bridge. Consider different types of bridges, such as beam, truss, or arch bridges. Build the Foundation: Begin by constructing the main supports for your bridge. Glue several popsicle sticks together side by side for a strong base. Assemble the Bridge: Connect the supports with horizontal and diagonal…

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...
