Framing & StructuralQuestion 363 of 700
Where a deck beam bears on a supporting post, what is the BEST practice for the connection?
a.Set the beam beside the post and rely on nails to hold it up
b.Balance the beam on top of a single nail
c.Seat the beam so it bears on top of the post (or in an approved saddle/cap) with a positive connection to resist uplift and displacement
d.Use adhesive only
Explanation
Best practice seats the deck beam directly on top of the post or in an approved post cap/saddle so gravity load bears in compression, with a mechanical connection (bolts or an approved cap) resisting uplift and sideways movement. Side-nailing the beam, balancing on a nail, or adhesive alone are unsafe connections.
