Abstract

This paper details the implementation of an innovative timber bridge technology developed for secondary road applications. A pilot bridge was constructed and field tested under loads comparable to required design loads. A through-girder primary system with transverse floor beams and longitudinal wood deck secondary system are involved. A unique steel hanger system for suspending the transverse floor beams and providing I-beam action under lateral load was configured. Results of the field load test program and analytical predictions from a computer model are described. The pilot bridge proved to be economically competitive and structurally effective.
