Abstract
Construction utilizing composite pultrusion technology incorporates an internal web structure in the elongated members themselves, increasing the strength-to-weight ratio, while providing support for joint notches due to the strategic positioning of the webs. The joints themselves are modified to accommodate the exiting of one or two members from the joint at an oblique angle to provide more construction flexibility to make diagonal braces, for example. The improved techniques are incorporated into a power transmission tower which takes advantage of the electrical qualities inherent in composites to produce a mechanically and electrically strong tower.
