Development of an integrated life-cycle management system for existing bridges

In our country, because there are a huge number of civil infrastructure systems, it will be becoming a major social concern to develop an integrated lifetime management system for such infrastructures in the near future. Then we need to develop an innovative system for long-term lifetime management engineering as Doctor for Infrastructure Systems. Namely, it needs to develop an integrated lifetime management system for civil infrastructure systems combined with the latest information processing technologies and intelligent health monitoring techniques, and also to establish the Doctor Degree for Civil Infrastructure Systems (INFRADOCTOR). This paper describes our Japanese strategy of life-cycle management in civil infrastructure systems for the 21st Century.
