Abstract:

This report includes fulfillment of Task 2.3 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

2.3 explores the effects of decreasing the rise (R) of an arch for a constant span (S) with a set of different earth

covers. It uses the finite element code (FE Code) by the University of Maine Advanced Structures and Composites

Center (The Center) that takes into consideration soil-structure interaction (Clapp and Davids, 2011).

A parametric study on a set of four bridge geometries given by rise-to-span (R/S) ratios of 0.30, 0.25, 0.2

and 0.15 was selected. In addition, two sets of cover were investigated for each geometry, 4 ft., and 8 ft.

respectively.

For a 40 ft. span bridge, decreasing the rise by 50% from 12 ft. to 6 ft. could increase the overall bridge cost by as

much as 16%.
