Wood Beam Saddle Connection

Wood Beam Saddle Connection

Wood Beam Saddle Connection

(OP)
Does anyone have a design example for the wood beam saddle connection shown in the attachment?  How would you determine what thickness of steel is required?

 

RE: Wood Beam Saddle Connection

1.  Determine the bearing stress on the plate from the beam, not exceeding the allowable perpendicular to grain bearing stress of the wood.

2.  Determine the maximum moment on the plate, either from wl^2/2 where the plate cantilevers the most, or wl^2/9 where the plate spans between the side plates.

3.  Take the square root of (the moment times 12, divided by 27).

The result is in inches and is the minimum plate thickness.  If the thickness is too great, make the length of the bracket longer to power the bearing stress, and recompute the thickness.

All dimensions in Kips and inches.

abusementpark,
Since you appear to have Breyer's book just go to page 14.23 to .26 for a detailed example.

What about the case where there is only a beam framing into the girder on one side?  How would the bearing stress distribution from the saddle plate to the girder look to maintain equilibrium?

That's not really the same condition.
