eccentric load on wood beams
eccentric load on wood beams
(OP)
I have a 15kip point load supported by an 8 3/4" wide glulam. The center line of the point load is off set from the center line of the glulam beam by 1 5/8" creating an approx 2000 ft-lb twisting moment. The glb has joists framed into it on the same side as the offset wich effectively braces the beam from twisting (I think). Do I need to be worried about this? Any information on how to calculate/analyze the significance of the twisting force would be appreciated.
Thanks.
Thanks.

Perhaps beefing up the joist at that point might be appropriate as well to add stiffness and ensure minimal rotation.
