Analysis of Steel Bridge Trunk Conditions Based on Loads and Corrosion Levels with Fuzzy Sugeno

Bridges built with reinforced concrete base materials, over time, the reinforcing steel is likely to corrode. Corrosion can be caused by the presence of electrolyte fluid that propagates around the reinforcement. The humidity level of the surrounding air can also trigger the corrosion of steel. Steel that has a high corrosion rate, can cause the bridge to collapse if it supports a heavy load it can result in a fatal accident. One solution is to check the level of corrosion on steel bridges regularly. The results of these checks can be used for further actions on steel. In this study, we propose a fuzzy method that is able to rate the corrosion rate of a steel point on a bridge. The input parameters of the proposed Fuzzy Logic are the load and corrosion rate by generating the condition of the bridge. The results of the fuzzy analysis are recommendations for the corrosion rate of steel, making it easier for field officers to carry out maintenance in accordance with the condition of the steel. The test results show that the Fuzzy method is able to analyze the condition of the bridge for the accident prevention process because the bridge collapses properly.
