Abstract
Allowable strength design is a method of proportioning structural members such that elastically computed stresses produced in the members by service loads do not exceed specified allowable stresses. Ultimate strength design is the method of proportioning structural members such that the computed forces produced in the members by the factored loads do not exceed the member design strength. In a corrosive environment, water may be absorbed into the open cracks and corrode the reinforcing steel. The use of aluminum for structural supports has a history in applications such as light poles, substation structures, and highway sign structures. Wood structures and poles should be designed and constructed in accordance with MOP 141, Recommended Practice for the Design and Use of Wood Pole Structures for Electrical Transmission Lines and NESC. The seismic qualification report or the equipment manufacturer should be consulted for seismic displacement requirements specific to the particular equipment.
