  • Abstract:
    This report includes fulfillment of Tasks 2.1 and 2.2 of a multi-task contract to further enhance concrete filled FRP ; tubes, or the Bridge in a Backpack. Task 2 is an investigation of alternative shapes for the FRP tubes with varying ; radii. Task 2.1 develops the computer model for FRP tubes with high gradients of fabric braid angle. Task 2.2 ; completes FRP tube shape optimization and laboratory testing of multi-radius arches. ; UMaine has developed and licensed a hybrid composite arch bridge system. The main structural bridge elements ; utilize a tubular braided composite fabric that can be bent to a desired geometry. To date, only arches of constant ; radius have been fully analyzed, which sometimes pose a handicap due to clearance and/or hydraulic opening design ; requirements. This project uses the finite element code (FE Code) written by the University of Maine -Advanced ; Structures and Composites Center (The Center) developed in previous work (Clapp & Davids 2011, Clapp & ; Davids 2011) that takes into consideration soil-structure interaction amongst other things, and extends it to ; incorporate the effects unique to a multi-radius arch. ; This project includes a parametric study, optimization of shapes and laboratory testing of multi-radius arches.
