RISA-3D Version 20 FAQs

By: RISA

Q: Are the files backward and forward compatible between versions?

A: Yes, the files are backward and forward compatible between all versions.

Q: Are there any new hardware requirements for RISA-3D v20 or later?

A: There are no new hardware requirements for v20. Learn more about Hardware Requirements.

Q: Can I have both RISA-3D v20 and v17 installed?

A: Yes! You can have both RISA-3D v20 or later as well as v17 installed allowing you to use either version. Both versions can be launched from the Start Menu.

Q: How do I use the Director tool to integrate the programs?

A: RISA-3D v20’s integrates with RISAFloor v16, RISAFoundation v14 and RISAConnection v13. You are still able integrate with previous versions of RISAFloor, RISAFoundation and RISAConnection by opening your model in RISA-3D v17.

Varying Soil Properties in RISAFoundation

While RISAFoundation has a Default soil properties (Subgrade Modulus and Allowable Bearing), it is possible to create regions of varying soil properties. This can be achieved by applying additional Soil Regions to your model. Simply select Soil Regions from the Insert menu, enter in the differing soil properties, and draw in the region. When completed the soil region will be displayed in orange. Please also note that a Soil Region may be used to model a location where there is no soil resistance. For example, if you have a portion of your foundation that does not bear on the soil, you can use a Soil Region drawn under that portion to model the gap. Simply set the Subgrade Modulus to 0 and the Allowable Bearing Pressure to something very small (since the program will not allow a zero input):…

Include Moving Load in Batch Solution

With the new release of RISA-3D v13.0, you now have the ability to include moving load combinations in a Batch solution. Just select which load combinations you want included in the Batch solution using the “Solve” checkboxes in the Load Combinations spreadsheet. Then run a Batch or Batch + Envelope solution. When complete, you will have two sets of results – those for the Batch and those for the Envelope solution. Since the moving loads still require an Envelope solution, this will be run automatically even if you only choose a Batch solution. The Envelope results will include all marked combinations. The Batch solution results will only include non-moving load combinations (for example, LC1 in the screenshot above). This way, you can see the Enveloped moving load results and the more detailed Batch results of your non-moving load combinations all at once without having to run multiple load combinations…
