How to Troubleshoot Unsupported Deck Edges
Have you ever received error message 2054 when modeling in RISAFloor?
If you've ever wondered what it’s like to be an industrial structural engineer, let me paint you a picture: Imagine juggling a dozen problems at once—steel frames, conveyor supports, pipe racks, tank foundations—all while trying to decipher a set of drawings that look like they were faxed from 1997. And, of course, every single solution is needed yesterday. But don’t worry! With the right tools (cough RISA and ADAPT cough), navigating this daily chaos becomes a lot more manageable. So, grab your coffee (black, obviously), and let’s walk through a typical day. 6:30 AM: Morning Coffee & Evaluating Additional Loads The first email of the day: “Can we add another 10,000 lbs of equipment to the mezzanine? What about seismic drift and vibration?” Instead of a lengthy hand calculation, you fire up RISAFloor and check gravity load distribution. Exporting to RISA-3D, you analyze modal frequencies and check if the additional weight will push the structure into an uncomfortable range for human occupancy. Seismic drift is next. A quick response spectrum analysis in RISA-3D confirms that the drift is still within acceptable limits. You send your report with confidence—no major framing changes required. 9:00 AM: Field Issue - Pipe Rack Base…

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.
An update to the Cold-Formed Steel Design Codes has been added to RISA-3D v16.0 and RISAFloor v12.0. Updated Codes include:
RISAFloor v11 includes the new Area Load Query tool which allows users to visually inspect the area loads applied to a floor level.
Basic Description Pattern based skip loading has recently been added into RISAFloor beam design. This can be turned on or off using the checkbox in the Solution tab of the (Global) Model Settings shown below.
