CELLULAR FIBER-REINFORCED PLASTIC SECTIONS FOR NEW AND REPLACEMENT BRIDGE DECKS

A new conceptual design for rapid replacement of short-span bridges for secondary roads is presented. Cellular FRP sections are used to construct the bridge decks. A simplified analysis/design procedure is developed based on a first-order shear deformation macro-flexibility (SDMF) orthotropic plate solution. The present approach will permit the designer to analyze and optimize various case studies before implementation in the field. In this study, FRP decks are fabricated by bonding side-by-side pultruded thin-walled box beams, and the decks are placed transversely over stringers. Experimental studies are conducted to obtain the stiffness coefficients, and future studies include testing of an FRP deck on FRP stringers under various loading and stringer spacing conditions.
