Video: Steel Member Design in RISACalc
Learn how to load and design individual beam and column steel members in RISACalc.
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…

Learn how to load and design individual beam and column steel members in RISACalc.
In RISA-3D when drawing members you must start with initial sizes. After loading and load combinations are completed the model is solved and then member design must be done, making sure that members pass for both strength and serviceability considerations. For both strength and serviceability...
RISA-3D includes the ability to design steel structures for seismic provisions found in AISC 341 and AISC 358 including moment frames and braced frames. For more information, review the video below.
Connection design according to the new AISC 360-16 (15th Ed.) Steel Manual has now been implemented in RISAConnection. To select this code for your design, simply choose either LRFD or ASD from the Solution tab within the Global Project Settings. The addition of the new 15th Edition code, includes...
The most recent release of AISC 360-16 (15th Edition) includes changes to connection design for rectangular HSS shapes with applied concentrated forces. These changes are now included in RISAConnection v10.
The release of RISAConnection v10 incorporates updates according to AISC 360-16 (15th Edition) including changes to HSS provisions as well as improved design for column webs subject to out-of-plane loading, in addition to other enhancements.
