Effects of Seismic Risk on Life-Cycle Cost Analysis for Bridge Maintenance

This paper aims to evaluate the effects of seismic risk on life-cycle cost (LCC) analysis for bridge maintenance. With a focus on deterioration due to corrosion of steel from chloride attack, LCC is examined for reinforced concrete (RC) bridge piers by consideration of the uncertainties emanating from earthquakes. Seismic risk is defined in terms of the seismic loss calculated by the earthquake motion with random quantities. Next, LCC is determined using the seismic loss, by which optimal maintenance plans are obtained using a genetic algorithm. It is concluded, based on numerical computations, that: 1) considering the seismic risk, it is possible to evaluate the effects of earthquake retrofitting methods; 2) the seismic risk greatly affects the selection of repair methods; and 3) the initial seismic performance is very important to establish earthquake resistant design.
