These round galvanized poles were designed to support a 20 foot tapered arm with a luminaire mounting height of 40 feet above the roadway. For the example, pole bending moments are calculated at ground level, where the concrete encasement terminates, and at the depth of maximum bending moment (zero shear). The high amount of carbon, also makes mild steel vulnerable to rust. 1 for the design of sign, luminaire, and traffic signal structures. Locate. American an steel).
