DescriptionDuring the 19th century, the economic material to build bridges was timber due to its abundant availability, cost, and ease of construction. Many of the well-known timber bridge types are the Burr arch, Town lattice, Howe, Queen and King type of trusses. This paper summarizes an investigation that was sponsored by the Federal Highway Administration and the USDA Forest Products Laboratory to recommend simple but accurate analytical techniques for improving the analysis of historic covered timber bridges. Within this manuscript, field testing results of displacements and strains for covered Queen-Post-Truss timber bridges was utilized to validate the results of the developed finite element model.
