Whole lifespan monotoring of concrete bridges
Civil structures are omnipresent in every society, regardless of culture, religion, geographical location and economical development. They affect human, social, ecological, economical, cultural and aesthetic aspects of societies. Therefore, no only good design and quality construction, but also a durable and safe exploitation of civil structures are imperative goals of structural engineering. The most safe and durable structures are usually those that are well managed. Measurement and monitoring have an essential role in structural management. In this paper, the importance and the benefits of monitoring during the whole lifespan of concrete bridges are presented. The lifespan of a concrete bridge starts with construction - pouring of concrete. Follow curing of concrete, testing of the bridge and most importantly the service period during service, the structure may be refurbished, strengthened or enlarged, according to necessities. Finally, at the end of exploitation, the bridge can be dismantled monitoring during each period of the bridge lifespan is important and can give rich information allowing a better understanding of structural behaviour and consequently better planned and less expensive management. In this paper, the importance of monitoring of each period of a concrete bridge's life is examined step by step, and illustrated an on-site example. The benefits of the information obtained by monitoring are apparent in several domains. First, it helps to improve and enlarge the knowledge concerning structural behaviour and makes accurate calibration of numerical models describing and predicting this behaviour possible. Thus, project and construction can be optimised in structural and economical aspects. Second, permanent monitoring can give early indications of structural malfunctioning. In this way, safety measures can be considered in time, and intervention an the structure can be performed immediately and with minimal economic looses. Experiences using a monitoring system designed for lifespan monitoring of concrete bridges is presented in this work.
