ABSTRACT

ABSTRACT: A huge number of infrastructures have been constructed with economic growth after the 2nd World War in Japan. Hereafter, it is an important issue how to maintain such a huge stock of infrastructures effectively. A lot of studies on the life cycle cost management (LCCM) and asset management (AM) of infrastructures are urged onward. Most of management systems developed up to the present, however, is not able to deal with the deterioration of performance such load-carrying capacity of structures and the change of service conditions. In this study, a new concept based on the performance-based maintenance of infrastructures is developed according to the concept of live design introduced for a method of the soft disaster prevention after the terror attacks in New York on 11th Sept. 2001. A new management process for maintenance of structures is described for meeting multiple demands during the reference time.
