| Abstract: | A new three-dimensional transducer system is introduced in this paper, which enables the measurement of six internal components
of strain tensor in concrete members. Laboratory tests and strain analyses were carried out to evaluate this tranducer system.
The results show that the system is effective in measuring internal strains of concrete members. It was then embedded in a
reinforced concrete bridge deck in Macomb County, Michigan. Field tests were conducted to measure the strains in the deck
under truck wheel load. The results were used to understand the deck's strain and stress behavior under truck wheel load. |
