## Abstract

In this paper a stochastic finite element model is developed to investigate the probability of failure of
cementitious buried sewer pipes under combined effects of corrosion and stresses. Using the developed model,
the effects of different random variables including traffic loads, pipe material and corrosion on the remaining
safe life of the cementitious sewer pipes are explored. A numerical example is presented to demonstrate the
application of the proposed model in evaluating the effect of the contributing parameters to the probability of
failure of concrete sewer pipes. The stochastic finite element model provides a practical tool for both designers
and asset managers to predict the reliable service life of the system.
