Abstract

Standard designs and specifications for hardwood glued-laminated highway bridges have been developed by Pennsylvania State University researchers. The research program for development of the standard plans and specifications, including species selection, laminating processes, treatment processes, and structural performance of hardwood glued-laminated girders, is presented. The resulting standard plans are for longitudinal girder, transverse deck red oak, red maple, or yellow poplar glued laminated bridges with clear spans ranging from 5.5 m to 27.5 m. Design loads are HS-25 or IML-80; live load deflections are limited to span/500. Standard designs are also included for 5.5 m to 7.3 m longitudinal deck glued laminated bridges for the same design criteria and hardwood species. The results of continuing efforts to improve the efficiency of the hardwood glued-laminated bridge designs are also summarized.
