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.
