The Time Dependent Reliability Analysis for the Deteriorated Reinforced Concrete Columns Using the Monte Carlo Simulation

摘要

This study was prosecuted to analyze a structural resistance degradation model for the existing column in the 3-story building to be remodeled. The probabilistic random variables in this study were dealt with an initial member strength, current maximum crack width, current density and diameter of reinforcement with elapsed time and corrosion initiation time, TDRA has been performed to calculate the reliability index, the failure probability, the degradation level according to the member strength loss in reinforced concrete columns due to corrosion of steel reinforcement.
