Laminated Wood Deck System for Folded Plate Girder

Folded plate girder (FPG) is a superstructure bridge system which involves a cold bend out of a single sheet of steel with an open bottom flange. The cold bend eliminates the costly and inconsistent shop weld found in traditional girders. The FPG concept works for both traditional construction and accelerated bridge construction (ABC). In traditional construction, formwork is needed along with the placement of deck reinforcement then the concrete is placed. In ABC, the deck slab is fabricated in the factory with transverse steel reinforcing bars extended outside the cured slab portion to form closure joint with adjacent deck slab then ultra-high performance concrete (UHPC) is placed at closure joints. In order to reduce the construction time further, a laminated wood deck is suggested in this proposal in order to further accelerate the on-site construction. Many advantages can be achieved by integrating laminated wood deck with FPG such as lighter prefabricated modular unit, easy fabrication of the modular unit, reducing on-site construction by eliminated construction joints, and suitability for rural regions where heavy equipment or cranes are not accessible. The proposed research suggests experimental testing and finite element modelling for a modular unit of FPG with laminated wood deck. In the suggested experimental work, large scale specimen will be tested under fatigue loading for service life design and under ultimate load for AASHTO strength design.
