Economical Solutions for Short-span Bridges Using Reinforced Glue Laminated Timber and Steel

The aim of this research was to develop new composite bridge concepts that are easily buildable and have a high grade of prefabrication by using reinforced glue laminated timber beams and steel trusses. All structural parts are designed so that minimal assembly is required and all elements are easily transportable. Glue laminated timber reinforced with synthetic straps was chosen due to its superior resistance, enhanced elastic behaviour under loading-unloading cycles, and other good mechanical properties, all based on previously conducted experimental studies, as well as other known advantages of classic glue laminated timber elements. A modular prefabricated bridge model was proposed that could cover small and medium spans and is both economic and easy to build. These timber beams combined with the rigidity and light weight of steel trusses could make an affordable and strong alternative for concrete slabs or other prefabricated elements that are mostly used for short-span bridges.
