| Summary: |
| This paper presents the active monitoring and damage detection systems for
reinforced concrete plate elements using piezoelectric patches. The method is based on monitoring of changes in wave propagation in reinforced concrete elements induced by piezoelectric actuators bonded or embedded inside the concrete structure. The quantitative value of damage is defined by damage index, where in this paper is presents a two-dimensional damage index adapted for geometrical characteristics of analyzed reinforced concrete plate-like elements. Because piezoelectric sensors/actuators remain permanently bonded or embedded in reinforced concrete structural elements, it is possible to actively monitor structural condition, to detect crack occurrence and monitoring further crack propagation. |
