ABSTRACT
In the following sections, an improved timedependent probabilistic model of the corrosion current density, which is an extension and simplification of those proposed by Liu & Weyers (1998) and Vu & Stewart (2000), is proposed and a corrosion model with the consideration of both uniform corrosion and pitting corrosion is also proposed. Next, the time-dependent reliability analysis of a chloride contaminated RC beam using the fourthmoment method (e.g., Zhao & Ono 2001, Zhao & Lu 2007) is illustrated in detail. Finally, the service life of the chloride contaminated RC beam is predicted using the present time-dependent system reliability assessment method.
