Konstantakopoulos and Michaltsos, 2010 proposed a mathematical model to investigate the dynamic behaviour of a combined cable system of bridges under moving loads. The stochastic perturbation technique and Monte Carlo simulation (MCS) method were used in the analysis. 2010 presented stochastic seismic finite element analysis of cable-stayed bridge material properties by random fields. Poor quality of construction and lack of regular maintenance leads to major retrofit in bridge structure. Over loading due to increase in wheel loads and regular exposure to aggressive external environment aggravate the corrosion of cables. Modern bridge infrastructure comprises of primarily concrete (reinforced or pre-stressed) and steel structures. The first modern cable stayed bridge is the Stromsund Bridge which was completed in 1950 in Sweden. Introduction Cable stayed bridges are gaining more popularity because the design of cables stayed bridges is governed not only by financial, practical and technical requirements but also by a great extent, by aesthetical appearance and architectural considerations.
