Description

8" x 6" EXTREN DWB® double-web beams replaced 10" wide flange steel beams in the 18 foot span, two-lane bridge. The bridge was upgraded from a 10-ton to 20-ton capacity after the rusted, severely deteriorated steel beams were replaced. Total construction time for steel beam removal and replacement with the composite beams and a timber deck was less than five days. The bridge utilized Strongwell's FRP hybrid 8" x 6" double-web beam that has carbon fiber in the flanges to increase the beam's stiffness to more than six million psi. The unique double-web design featuring internal flange stiffeners also provided a beam with less than 1/2% rotation under three-point loading in laboratory tests.
