structural engineering.

I am designing connection for two wood beams connected to each other by bolts or lag screws. The lag screw or bolts are provided in three rows and at a certain spacing along the length of beams. How the check for the connection strength if a udl is acting on the combined beam along the length.

Thanks.

You should consider uploading a sketch of your condition, to get the most helpful responses.

If the UDL is acting evenly on the combined beam (and the connected beams are of the same section), then there is no structural need for the connection unless perhaps to provide additional stability for slender beams.

If the beams are of different sections, or if the UDL is applied directly to one beam and not the other, then there are calculations that can be performed.

I am attaching the image of the connection.
The udl on the beam is due to heavy load from the framing.

In addition, you might try 2 lines of bolts staggered to reduce the number by more than half. The fasteners serve little purpose.

Please confirm the direction of the load; what do you mean by "along"?

I agree with Dik. The connections will hold the beams together, but seem to add nothing in the way of strength. The beams should be treated as (2) separate beams.

I agree with Dik and WMArmstrong.
