Cap Plates and baseplates
Cap Plates and baseplates
(OP)
Does anyone know where I can find a design procedure for column cap plates when beams or joists bear on them? I would also like to find a design procedure recommended for bearing plates under columns supported by a transfer girder.
Thanks,

Some cap plates, however, do require a thickness calculation. The one instance that I can think of is a small column bearing on a cap plate of a larger column. I am sure there are a few other instances also.
I would suggest developing the load path and reason out how the stresses would work.

1. Make plate as wide as the beam bottom flange.
2. If column is wider than beam bottom flange, then the cap plate is made larger to accommodate welding to the column.
3. Select method of fastening beam to cap plate.
4. I try to match the cap plate thickness to beam bottom flange thickness.
5. For special conditions where you induce bending moment on the cap plate, then analyze it and determine plate thickness by design.
