Abstract

<p>Aging infrastructure is becoming a major concern in the engineering practice, thus, there is a need for the development of a suitable reliability-based analysis of aging bridges subjected to scour hazard. This paper proposes such analysis based in a time dependent stationary deterioration process for the scour demand and a random independent variable for the bridge foundation capacity. Reliability is computed using direct integration for discrete times. Based on the results, an exponential function is proposed to estimate the decrease in reliability due to the accumulation of scour around a bridge pier through time.</p>
