Steel plate below glass rail shoe
Steel plate below glass rail shoe
(OP)
I have to design the connection for a glass rail shoe to a wood beam. I used a steel plate on top of the wood beam and the glass rail shoe has screws to this plate. The shoe connection to the steel plate comes from the glass rail manufacturer specs. I basically designed the connection of the steel plate to the wood beam to resist 50plf along the top of the rail. Shoe and steel plate are continuous. My steel plate is 5/16" thick x 3.5" wide. The lags are at 12"o.c. 3/4" from each edge. I am stuck on how to check the adequacy of the plate and the bearing perpendicular to the wood.

3/4 inch in from the edge of a wood beam is very small for a lag bolt, which works by trying to split the beam down the grain. A through bolt at least tries to compress (squeeze together) the wood fibers rather than spread them further apart.

Racookpe, the lags are 1/4" dia and working in tension.

We can’t see it from here, so we have no idea what you are talking about. So.... the first thing you are missing is a good sketch showing us what you are dealing with. That should include loads, sizes, dimensions, reasonable proportions, materials, etc., etc.
