This research study focused on the long-term and repeated load behavior of wood-concrete composite beams in which the wood layer is composed of recycled utility poles. Previous research studies have found this type of a beam to have high efficiency and to be a potentially viable replacement for short span bridges on low traffic roadways. Since both wood and concrete exhibit time-dependent behaviors, it is necessary to examine the effects of sustained and repeated loads on the composite beam.
