Defining Connections: Column to Beam Connections
Member Configuration The connection rule must be applied at the end of the beam (not the column).
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 Version 12 now supports skewed shear tab connections. With this enhancement, engineers have the option to skew a wide flange, a tapered wide flange or a channel beam with the following supporting members:
Now available in RISAConnection v8: the ability to design a Two-Sided Shear Connection. Building from our existing one-sided shear connection (for column/beam & girder/beam), this connection now offers the user a powerful tool to provide clip angles to both sides of the column or girder web.
