ANSI/TPI 1 Scope. The TPI 1 standard establishes minimum requirements for the design and construction of metal plate connected wood trusses. This standard describes the materials used in a truss, both lumber and steel, and design procedures for truss members and joints.

ANSI/TPI 1 establishes minimum requirements for the design and construction of metal-plate-connected wood Trusses. This Standard describes the materials used in a Truss, both lumber and steel, and design procedures for Truss members and joints.

ANSI/TPI 1 National Design Standard for Metal Plate Connected Wood Truss Construction is the industry’s consensus standard and is referenced by the IBC and IRC. The following text is a compilation of the requirements provided in ANSI/TPI 1-2007, Chapter 2, with permission from the publisher, the Truss Plate Institute (TPI), www.tpinst.org.

The ANSI/TPI 1 standard establishes minimum requirements for designing and constructing metal-plate-connected wood trusses. It describes the materials used in a truss, both lumber and steel, and design procedures for truss members and joints.

For the truss industry, there is a new truss design standard that was just released the last week of December. Still hot off the press, the ANSI/TPI 1-2014 standard is a revision to the 2007 edition and is referenced in the 2015 International Building Codes.
