Abstract: The disclosed technology includes a tripod reinforcement beam for reinforcing a tripod grillage of a transmission tower. The tripod reinforcement beam may include top and bottom faces that are substantially planar surfaces, a rear face disposed substantially perpendicularly between a rear edge of the top face and a rear edge of the bottom face, and a front face disposed between a front edge of the top face and a front edge of the bottom face. The rear face may include first and second substantially planar rear face portions and an angled rear face portion. The front face may be include first and second substantially planar front face portions that are oriented parallel to the first and second substantially planar rear face portions, respectively.
