Evaluation of stress-laminated T-beam bridges constructed of laminated veneer lumber
Growing interest in wood bridges during the past decade has led to the use of new wood products and innovative designs for bridges. One new wood bridge system that is becoming increasingly popular involves solid, laminated veneer lumber T-beams that are stress laminated together. As part of the development of these bridges, an evaluation program to
monitor field performance of six bridges was implemented.
This paper describes results of field performance related to bar force, moisture content, and condition assessment, with presentation of load test and analytical evaluations for two of the six bridges.
