Subject: strengthening steel joists for shear
Hi,
I'm looking for some guidance on strengthening existing steel floor joists for shear and have a few questions.
For a wide flange beam, we'd typically add some shear stiffeners or gussets. Is the same approach applicable for an open web steel joist? Can i just add some angles to the web?
How about reinforcing at the bearing ends, can i just add a piece of hss 2.5 x 2.5 to either side of the joist seat?
I appreciate any comments you may have.
Thanks,
Alden
