Performance Analysis of Suspension Bridge: A Reliability Approach

This paper addresses the overflowing issue of a suspension bridge in context of system’s reliability measures. Suspension Bridges have proved to be the most stable structure in the never-ending list of bridge constructions. Unfortunately, various effects of operational and environmental variability (factors) have posed several challenges to the reliability of the whole structure. History has encountered various failures of the suspension bridges with no early prediction and aftermath analysis. This paper investigates the ability to use Markov process for degradation modelling of suspension bridges by taking some of its important section namely Tower Foundation, Tower, Anchor, Cable, Deck along with human error. Here we identify various factors responsible for deterioration of the major components of bridge, which further affects the working of the mainframe structure.
