Paper Abstract

In order to maintain sustainability of infrastructures in which have significant influence to social lifelines, an economical and rational maintenance management system is absolutely needed. Maintenance management of infrastructures and reduction of their life cycle cost (LCC), become serious problems those have to be solved urgently. In this paper, Structural health monitoring based maintenance (SHMBM) aimed to reduce structure’s life cycle cost is proposed. Theoretical background of SHMBM and contribution of monitoring information in LCC reduction are reviewed. As the tools to retrieve the structural deformational properties information, the intelligent sensory principles and their sensory system are introduced such as GPS based MMS monitoring technology, peak memory sensory technology, elasto-magnetic sensory technology and fiber optical sensory technology. Their reliabilities were verified by some verification test and field application test. Some examples of SHMBM application in the monitoring of structural properties are also described as well.
