Beam to Masonry Wall
Beam to Masonry Wall
(OP)
I have a W section which is tying in to a parallel 8" masonry block wall. The wall is existing. I am planning to place Reinforced CMU below the seating of the beam. I would like to have a 4" bearing surface but it's not clear how many blocks I should replace with the CMU to provide a sufficient bearing surface. The reaction at beam end is about 10kips. Any help would be great. Thanks.

You may detail a steel bearing plate or a steel plate embedded in the end of the wall. The beam would frame into this and have a single shear plate connection. The bearing plate will keep you from inducing addional moment in the wall due to an eccentric connection. The shear plate would probably allow for more beam end rotation through bolt slip. Either way, use a bolted connection with slotted holes to allow for expansion of the steel beam. Make sure the bolts do not get overtightened, and you may even use a teflon washer between the nut and the flange if you use the bearing condition. No matter what you do I would make sure you have a good two or three filled and reinforced cells at the connection.

Uplift resistance may be achieved by vertical restraint strapping, which should be sufficiently long to mobilise the dead weight of a section of the masonry panel sufficient to resist the uplift.
