Evaluation of the Susceptibility of Failures in Steel Structures of Transmission Lines

[摘要] Overhead transmission lines are exposed to several risks associated with its surroundings, changes in design characteristics and climatic variations. Many times, these risks can lead to serious damages, incurring in drop towers. So, this work has the objective of evaluation of the susceptibility of the structures to suffer mechanical efforts above the projected, which can lead to their falls. It is made taking the database of the structures and information about the ones that had suffered damages and using the Rough Sets Theory and the Regression Logistic Method to extract knowledge about what parameters and variables influence the mechanic behavior of the operation lines and can be applied to diagnose possible dropped towers. The results are obtained using the history of two thousand steel structures currently operating in the state of Parana, from which rules are generated to identify the susceptibility of fall...
