Structural health monitoring of RC structures under seismic loads has recently attracted attention in the earthquake engineering research. In this paper, a piezoceramic-based device called "smart aggregate" was used for the health monitoring of RC frame structures under earthquake excitations.
In this experiment, the concrete grade is C20 and the concrete mix proportion is 0.47:1:1.34:3.13. The fabrication of each cubic meter of concrete requires 190 kg water, 404 kg cement, 542 kg sand and 1264 kg stone. The water cement ratio is 0.47. Concrete specimen material parameters are shown in Table 1.

The deterioration and aging of the infrastructure in the U.S. have become a crucial issue, especially for highway bridges and nuclear power plants. The reliability and safety of existing structures are affected by growing populations and limited resources. This issue has gained significant concern during the last two decades and efforts are being conducted to accelerate the improvement of
5/9/2020 · A reliable novel monitoring approach is developed to assess the structural condition of reinforced-concrete bridge elements. The approach is based on combining acoustic emission technique and strain gauge measurements, and it is illustrated by a case study of a composite steel–concrete viaduct in service since 1957.
The authors conclude: "In structural health monitoring application of distributed BOTDR strain measurement, the fiber optic sensing cable should be installed carefully so that the initial strain profile is as uniform as possible.
