  • Italian architect Ande Palladio developed three forms of the basic truss element—the rigid triangle. These forms are believed to be the earliest examples of trusses used scientifically.


  • The Howe truss won a United States patent, and following Palladio’s work, became the earliest form of a simple truss created for long-span bridge construction.


  • Thomas W. Caleb Pratt patented another combination wood and iron bridge truss. This truss differed from the Howe with diagonal webs of iron (for tension) and verticals made of wood.


  • A. Carrol Sanford invented the metal truss plate with teeth called the Gri-P-Late.


  • Sanford’s Gri-P-Late thrilled Miami building officials, and he was issued the first Engineered Bulletin for his product by the Architectural Standards Division of the Federal Housing Administration on July 13.
  • J. Calvin Jureit, founder of Gang-Nail Systems Inc. (now MiTek Industries), created the Gang-Nail plate, the first metal connector plate for trusses that did not need supplemental nail fastening. The plates were pressed into the lumber using a concrete vertical hydraulic press and steel table precision jigs.


  • Klaisler Manufacturing opened its doors as one of the first truss roller manufacturers.


  • CLT Continuous Lumber Tester invented at Potlatch Forests, Lewiston, ID. Patented by Harold Keller.

Within a few years, these programs were converted to run on IBM 1130 computers, and other truss plate manufacturers followed Gang-Nail’s lead.
  • Robert Brooker developed the first truss engineering computer software package sold with the computer source code, based on TPI’s 1974 design criteria.
