Abstract

Various protective barriers are used in practice to protect reinforced concrete and steel structures in severely aggressive environments. In this paper, we consider a multi-layer corrosion protection system (CPS) which is modeled as a three-unit of non-identical components cold standby system. The system can be maintained or non-maintained. In this system it is assumed that degradation and renewal (if necessary) rates of all components are both exponential and different. After repair the components are "as good as new". Under these assumptions, using the Markovian degradation/renewal process some important reliability indices such as the system reliability, the point and steady-state or limiting availability, mean time to failure are defined. The performance of corrosion protection system is illustrated by numerical example.
