Abstract
A composite beam system that can be used for the framing system in bridges or buildings and provide enhanced corrosion protection includes a fiber reinforced plastic beam shell with compression and tension reinforcement. The compression reinforcement consists of portland cement concrete which is pumped into a profiled conduit within the beam shell. The conduit for the compression reinforcement is profiled to optimally resist the internal forces in the composite beam for a particular loading. The tension reinforcement consists of carbon, glass or steel fibers anchored by wrapping around the ends of the compression reinforcement. The positioning of the tension reinforcement is optimally designed to equilibrate the internal forces in the compression reinforcement. Each composite beam has a series of internal vertical stiffeners which are perpendicular to the sides of the beam shell. The composite beams can be used in the construction of bridges and buildings using conventional erection techniques. The compression reinforcement can be installed into the beam after it is erected. This results in a very light weight structural member for transportation and erection.
