An Optimization of Strengthening Position to Avoid Progressive Failure in Utility Poles.

Abstract

In the past several years, a large number of electrical poles have been failed. Most of failure caused by car crash, truck pull electrical cables or communication cables and tree fall over electrical poles and cables. As a result, affected a wide area. People suffer from lack of electricity for a long period of time and danger from electrical poles fall over and electric leakage. The study approach to prevent electrical poles failure. The study will focus on ways to reduce impact of electrical poles failure. The concepts is determine break point on electrical poles higher than ground level that can reduce force which transfer to next electrical poles. When electrical poles fall and transfer force to next electrical poles on both side. Both electrical poles are loaded and fail at fixed point by reinforcement. It will make the next electrical poles stop falling. This principle leads to simulate the electrical poles structure models by finite element method to compare analysis from finite element method and hypothesis and optimize reinforcement position.
