Steel Design per AISC 15th Edition Steel Manual now Available
The new AISC 360-16 15th Edition changes have been implemented into RISA-3D v17.0 and RISAFloor v13.0.
The ASCE/SEI 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures introduces significant updates from ASCE 7-16. The most notable changes impact wind and seismic provisions, along with new load combination rules that directly affect structural analysis and design. With the release of RISA-3D v23, engineers can now take advantage of these updates directly within their workflows. Why This Matters for Engineers? The most impactful provisions of ASCE 7-22 — wind, seismic, and load combinations — are now supported in RISA-3D v23, ensuring your projects remain compliant with the latest building codes and IBC 2024 adoption. Download the latest versions of RISA that supports ASCE 7-22 below. 1. Wind Provisions Key changes in ASCE 7-22 affect wind speed maps, velocity pressure equations, and roof zone definitions. Topic ASCE 7-16 ASCE 7-22 Design in RISA Wind Speed Maps Based on 2016 hurricane data Updated hurricane & transition zone maps RISA-3D generates wind loads per ASCE 7-22, reflecting updated maps Velocity Pressure (Kd) Included directionality factor Kd removed Automatically handled in RISA-3D wind load generation Roof Zones Based on h/B ratio for hip roofs h/B removed; new GCp values and roof zoning RISA-3D applies updated coefficients for accurate roof…

The new AISC 360-16 15th Edition changes have been implemented into RISA-3D v17.0 and RISAFloor v13.0.
RISAFloor v13.0 now includes the added ability to graphically copy elements from one floor to another floor. This feature will expedite the modeling process by giving designers more control over which beams, columns, walls and joints are carried over to another floor. To access the tool, click on...
For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design.
Have you ever received error message 2054 when modeling in RISAFloor?
RISAFloor column results are available in the results spreadsheets, but you may not be aware that you can also graphically review the input and results of columns. To do this you need to customize your toolbar, which is an option available in the Tools menu:
RISAFloor does not record the applied deck in a spreadsheet. To simplify modeling, it instead assumes a default deck is drawn within the entire diaphragm edge. If you have an area that will be a different deck or a different span direction, then you are free to draw in over the default. Whatever is...
RISA is pleased to announce the release of the latest RISA-Revit Link which is compatible with Revit 2020. The RISA-Revit Link v19.0 allows seamless integration between RISAFloor, RISA-3D, and Autodesk Revit. The latest version now includes the ability to import beam reinforcement details from...
The BS EN 1992-1-1:2004+A1:2014 has been implemented in RISA-3D version 16.0 and RISAFloor version 12.0. To select this code for your design, simply open the Model Settings and under the Codes tab select BS EN 1992-1-1:2004+A1:2014 for concrete:
The new TMS 402-16 Masonry Code (formerly designated as ACI 530 and ASCE 5) have been added to RISA-3D v16.0, RISAFloor v12.0 and RISAFoundation v10.0.
