Re: Brick veneer support guidelines

[Subject Prev][Subject Next][Thread Prev][Thread Next]
ACI 530 (Masonry code) limits vertical deflection of beams and lintels
supporting masonry to L/600 or .3" when loaded with dead and live loads.

Some people will not include dead loads that are already in place prior to
the placement of the masonry (i.e. weight of beam, slab).

My own opinion is to use the live load, the weight of the masonry and any
superimposed dead loads that will not be in place prior to the placement of
the masonry.

You can also look up tech notes at the BIA (Brick Institute of America) at

Hope that helps,
