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.

RISAFloor & RISA-3D: Two Buildings on the Same Podium

RISAFloor is the RISA Building System’s floor design software which allows users to design with composite decks, elevated concrete slabs and more. When paired with RISA-3D, the two create a complete solution for the analysis and design of multi-story structures, including two buildings on the same podium. Equivalent Lateral Force/Static Force Procedure After the definition of slab edges and the application of diaphragms in RISAFloor, RISA-3D is used to determine the different lateral forces that need to be attributed to each individual diaphragm that exists at each elevation. These story forces can then be displayed graphically (as shown below) per diaphragm at each elevation. Dynamic Analysis If your building requires a dynamic analysis, mode shapes can be calculated and displayed in the same fashion as they are for a single structure. Similarly, building frequencies and mass participation’s are just as simple to retrieve by simply choosing “frequencies” or “mode shapes” from the Results Toolbar or the Results menu drop-down. Intermixing Diaphragm Types RISA also allows users to analyze with different diaphragm types (flexible, semi-rigid, rigid) at the same elevation of your separate buildings. Using RISAFloor paired with RISA-3D, engineers can analyze and design complex structures with this configuration. In addition,…

Expanded Load Categories in RISA-3D and RISAFoundation

New to RISA-3D v19 and RISAFoundation v13 is the ability to apply up to 100 "Other Load" Categories. Previously users only had the ability to add up to 10 "Other Load" Categories. The expansion of "Other Load" Categories gives the user more flexibility to be able to apply and organize the loading in the model to fit their needs. To apply "Other Load" Categories in RISA-3D, simply select the "Other Load" Category from the drop down menu when drawing loads. To include the "Other Load" Categories in the Load Combinations in RISA-3D, you may either enter OL1-OL100 in the BLC field or you can select the ellipses to prompt the Set BLC Entry and select the "Other Load" Category from the drop down menu. To apply "Other Load" Categories in RISAFoundation, choose the "Other Loads" from the dropdown on the Distributed Loads Spreadsheet (or in the left Properties Toolbar) and choose a value between 1 and 100. To include these "Other Loads" in Load Combinations, you may either enter OL1-OL100 in the BLC field or you can select the red arrow to prompt the Set Category Entry and choose the "Other Loads" radio button and input a value between 1…
