Degradation of performance and deterioration of different components of reinforced concrete (RC) structures increase with the age of structure. This deterioration of reinforced component depends on several parameters. However, modeling service life of RC structure by considering all the parameters is a difficult job, as most of the parameters are uncertain in nature. Probabilistic models account well for the uncertainties in the parameters responsible for deterioration of RC structures. This paper presents a review of several recent service life models developed using probability based concepts.

[1] Resilience characterizes the recovery capacity of repairable systems from the failure state to the safe state. Resilience has been recognized as a meaningful probabilistic indicator for evaluating risk-cost trade-offs in water resources systems. Traditionally, the resilience in the discrete time domain is estimated by sampling methods, which have a high computational expense. No single approximation approach has been well developed for estimating resilience, even under stationary conditions. This paper proposes two practical approximation methods for estimating the lag-1 resilience in the discrete time domain. Both methods are theoretical developments, one based on a bivariate normal distribution, and the other based on a stochastic linear prediction of the performance function using the mean point of the failure domain. The foundations of both methods are the first-order reliability method and the periodic vector autoregressive moving-average time series model. The methods are robust for a wide range of problem characteristics and are applicable for systems facing stationary or nonstationary input conditions.

Abstract-Steel structural connections are integral parts in steel structures. They are widely used in building frames to join different structural members together as well as to support gravitational load, shear load and bending moment and to transmit them to the adjacent structural components. However, gradual thinning of steel due to corrosion damage reduces their load bearing capacity, loses structural connectivity and subsequently jeopardises the structural integrity of the entire structure. This paper presents a remaining capacity assessment method, namely timedependent yield moment model, for steel structural connection derived analytically based on a time-dependent corrosion rate model and yield-line theory. Time dependent yield moment model of steel structural connection is derived analytically as a function of time and geometric parameters of the plate. Solution to a wide-flange-section-to-column-baseplate connection subjected to minor axis bending moment and flush endplate beam-column connection subjected to in-plane bending moment is presented. Results of the analytical expression are compared to a three-dimensional nonlinear finite element model and good agreement is obtained. The proposed model may contribute to the prediction of remaining strength and repair schedule of corroded steel structural connections.
