Simpson Strong-Tie®Yield-Link® Moment Connection Available in RISA-3D
The release of RISA-3D Version 19 includes the introduction of Yield-Link® Moment Connections, developed in conjunction with Simpson Strong-Tie®.
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…

RISAConnection v11 now includes the ability to design Column to Beam Column Cap Flange Plate Moment Connections according to AISC 360. This widely requested feature allows users to define the beam as a wide flange and the column as either a wide flange, tapered wide flange or HSS tube. To begin,...
Wide Flange beam to HSS Tube column moment connections can now be designed in RISAConnection version 9 with both the US and Canadian design standards. HSS tubes may be selected as the supporting column member on either of the two moment connections:
Wide Flange Beam to HSS Tube Column Moment Connections can now be designed in RISAConnection version 9. HSS tubes may be selected as the supporting column member on either of the two moment connections:
RISAConnection v8 now offers weak axis moment connections with beams framing into the web of a wide flange column. Previously, connections were only permitted to frame into the column flange. This additional feature will allow users to change the orientation of their wide flange column.
