ABSTRACT

The Life-Cycle Cost (LCC) concepts and methods have remarkably advanced in the field of civil infrastructure (Frangopol & Furuta 2001). Many international symposia and workshops have been held all over the world. The basic concept and methodology of LCC itself are not new and were already adopted several decades ago in the fields of electrical and mechanical engineering. In the field of civil engineering, seismic risk analysis was established on the basis of LCC. However, it is noted that the seismic risk analysis has not paid much attention to the structural maintenance activities.
