• Abstract:
  This report includes fulfillment of Task 1 of a multi-task contract to further enhance concrete filled FRP tubes, or ; the Bridge in a Backpack. Task 1 investigates and develops a feasible solution for splicing the concrete filled FRP ; tubes. This will allow use of this bridge type in longer spans. ; A splicing solution using a combination of internal rebar reinforcing and an outer FRP collar to connect the two ; sides of the arch is developed and tested. The outer collar sustains the loads during filling of the arch with concrete. ; The internal rebar provides the long term load carrying capacity with all dead and live loads. ; Results from the laboratory tests and analysis show the splice detail is structurally adequate but is conservative.
