• Abstract:
  This report includes fulfillment of Task 8 of a multi-task contract to further enhance concrete filled FRP tubes, or ; the Bridge in a Backpack. ; One recurring question has been its performance in fire conditions, mainly small campfires and handheld torches. ; Previous testing for this technology at the Composites Center has looked at its ignitability using small coupons or ; sections of the concrete filled arch. This task provides a more extensive look at the performance of this particular ; composite system. This project consisted of three phases including: laboratory coupon tests; large scale field fire ; tests of a traditional steel girder and concrete deck specimen and a hybrid composite arch test specimen; and a ; laboratory structural test to evaluate residual capacity of the composite arches after the field fire test. The principal ; objective of this project was to compare the performance of the two full scale test specimens when exposed to the ; same fire environment.
