Abstract

A composite I-truss is provided, that comprises a pair of top and bottom flanges and an extending intermediate web having a first end secured to the first flange and a second end secured to the second flange. Each flange comprises one or more longitudinal beams secured to the flange connectors. The web comprises at least a pair of flange connectors extending away from the flange and toward the web. The web comprises a plurality of linking struts located at a plurality of longitudinal positions along a length of the I-truss and connecting the flange connectors of the first flange to the flange connectors of the second flange.
