The Truss Plate Institute is happy to announce the release of the new ANSI/TPI 1-2014, "National Design Standard for Metal Plate Connected Wood Truss Construction." This publication is an update to the ANSI/TPI 1-2007 and is now available for purchase online from the Truss Plate Institute at our online store. The new ANSI/TPI 1-2014 standard is available in hard copy or in a downloadable electronic form and comes with a Commentary & Appendices.
New in the 2014 edition are provisions for Load and Resistance Factor Design (LRFD) for metal plate connected wood trusses, expanded deflection limitations to accommodate provisions often specified by Building Designers, and a reorganized Design Responsibilities chapter. The Commentary, that is included with the purchase of the Standard, provides a complete list of the non-editorial changes that were made in the 2014 edition (also available HERE). The 2014 edition of the TPI 1 standard is referenced in the 2015 editions of the International Residential Code and in the International Building Code.
