Abstract

In recent years, the importance of Structural Health Monitoring has been recognized but an SHM system still confronts serious problems related to complexity and cost in practical use. To solve these problems, the authors have developed the simple and smart SHM system by integrating self-diagnosis material and a wireless data measurement device. By installing this SHM system, it is possible to detect damage to structures easily even after a large earthquake or other disaster and also to inspect possible deterioration of a structure in a short time. As a practical matter this SHM system is expected to be very reliable, and when it is mass-produced it should have a low cost. To confirm the utility of the damage detection of a building after a large earthquake, the pre-production system was installed in a specimen simulating the beam-to-column connection part in a mid-size conventional reinforced concrete building, and a loading test was performed on the specimen. The effectiveness of the proposed system is demonstrated by the test results.
