Abstract
Evaluation of the life cycle cost for the infrastructure is required for decrease of the construction cost. The risk cost is the most laborious work in the determination of the life cycle cost for bridge structures. The risk cost has not been evaluated even for the members of the structure. The present study aims to predict deterioration process and to propose an evaluation procedure for the risk cost of RC slabs under repeated fatigue loading. The present paper indicates the results of the calculation of the failure probability of slabs with different thickness and replacing cost including profit-and-loss costs. These provides the risk cost for RC slabs under fatigue loading.
