Abstract:

The concept of durability design for concrete structures including bridge structures is proposed on the basis of comprehensive evaluation of materials, design details and construction works under a certain environmental condition. The fundamental design philosophy has been developed by the authors and was principally accepted in the Subcommittee on durability design for concrete structures in the Japan Society of Civil Engineers (JSCE). In the Subcommittee, where H. Okamura is a chairman and M. Kunishima is one of the members, the new concept on durability index has been introduced. The methodology to calculate the index quantitatively has been discussed and the proposed recommendation for durability design of concrete structures shall be published in 1989 by the committee on concrete in JSCE. This paper describes the framework for the new durability design of concrete structures and the some case studies for its applications to practical concrete bridge structures.
