Estimation of Bridge Life Cycle MR&R Costs Using a Reliability-Based Model

Rong-Yau Huang and I-Shiang Mao
Abstract—This study proposes a systematic approach to estimate the MR&R cost of bridges using a reliability-based model. The approach first identifies a group of similar bridge samples to describe how the target bridge deteriorates in terms of reliability indices. The cost is then accumulated while each MR&R action is assumed to be taken over its lifespan. Afterwards, Monte Carlo Simulation is applied to generate the probability distribution as a stochastic result. Bridge expansion joint is employed as an example to demonstrate and to validate the developed approach. Results show the estimation of maintenance cost for the expansion joint of the bridge example forms a lognormal distribution with a mean of 120,768 TWD.

Index Terms—Bridge, cost estimation, deterioration.
