Using Angles for a Coped W-Beam Seat
Using Angles for a Coped W-Beam Seat
(OP)
I'm designing a crane bridge beam with a coped beam seat for the bridge. I've always used a flat plate as an intermediate flange for the bearing plate. The contractor is asking if they can use two angles as the intermediate flange for the bearing plate with the web of the bridge beam sandwiched instead of using one flat plate as the bearing plate. Is there any concern with this approach? Never done it this way.
Thanks,
Thanks,

I guess I’ve seen that detail too, and more than likely used it too, in one form or another. The one advantage of the angles, is that they add considerable extra web material/thickness in an area of the beam where the shear is high and the shear stresses may be quite high because of a deep cope. If the vert. legs on the angles are to long, you may not be able to get into them to weld them to the beam web, the beam flg. will be in the way for welding access.
