Responsibility For Multi Ply Girder Truss Assembly
I am reviewing a truss package that includes multi-ply trusses. Where do I find the requirements for the attachment of the individual trusses to each other (nails and/or bolts)? Is this a requirement that the structural engineer of record needs to supply or is it the responsibility of the truss manufacturer to design?
The responsibility for specifying the ply-to-ply connection requirements of trusses belongs to the truss designer, as specified in SBCA’s TTB – Standard Responsibilities in the Design and Application of Metal Plate Connected Wood Trusses; the Truss Plate Institute's ANSI/TPI 1, IBC 2012 2303.4, and IRC 2012 R502.11.1; and IRC 2012 R802.10.1.
