AISC 341-16 & AISC 358-16 now included in RISA-3D
The AISC 341-16 and AISC 358-16 Edition changes have been implemented into RISA-3D v19.
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…

The AISC 341-16 and AISC 358-16 Edition changes have been implemented into RISA-3D v19.
The new ACI 318-19 code has been implemented into RISA-3D v19, RISAFloor v15, and RISAFoundation v13. One of the biggest changes between the ACI 318-14 code and the ACI 318-19 code is the shear contribution provided by the concrete, Vc.
Recent tests and analytical results for concrete columns have indicated that considering shear along each centroidal axis independently can be unconservative. Therefore current versions of RISA-3D, RISAFloor and RISAFoundation have included the consideration for the interaction of shear forces...
The Quick Start Course is a 4-hour introduction to the basic features and functionality of RISA-3D that utilizes expert instruction and example models to familiarize users with the user interface as well as the main workflow of modeling, loading, analyzing, designing and documenting a model in...
Watch the recording of our webinar to learn how new versions of RISA-3D, RISAFloor, RISAFoundation and RISAConnection provide users with expanded design capabilities, improved product integration and new features including:
Overview FRP or Fiber Reinforced Polymer (thermoset) composite materials are becoming more and more popular in the construction world of today. There are many reasons for using composite materials, which go beyond the scope of this article but suffice to say that composite/FRP materials are now...
If you have utilized Hold-Down's in RISA-3D, you have mostly likely noticed that a value of CD is reported for each selection in the database. However, it may not be clear how it is being used?
In the Node Reaction spreadsheet, all reactions from node-based boundary conditions are reported. If you look closely at some models, there may be wall panel labels in the Node Reactions spreadsheet as well. This may cause users to ask the question:”what are these reaction values for a...
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.
