jack truss connection to girder truss
(OP)
Do you find jack trusses are only connected to girder trusees by toe-nailing? shouldn't bearing be provided with a hanger? Is this connection typically the buidling engineer's responsibility or truss engineer?






RE: jack truss connection to girder truss
I also specify all TRUSS TO TRUSS connections to be designed and specified by the TRUSS ENGINEER. I had too many experiences early on in my career where the truss designer changed the layout I had originally predicted on my dwgs which created a large headache after the dwgs were done.
But all the truss connections to the main structure are specified by the EOR. I put a note that some of the connections may be modified based on the final truss design package. As stated above, they may change the layout to be more economical and I gave up predicting what that may be...

RE: jack truss connection to girder truss
I have seen both toe-nailing and hangers. It really depends on how long the jack trusses are and the deisgn loads (wind, snow, etc.).
Sim to what A2mfk said, toe-nails can have installation issues (can damage wood, etc.) plus over time the wood will shrink and pull these nails with it. 'Basic' hangers (not skewed/sloped) are not that expensive for these low loads.
