| Abstract | Nowadays, Structural Health Monitoring (SHM) has been developed the ways to detect structural damage by using structural modal properties which is called vibration-based damage detection method to indicate location of damages and to identify level of damages. However, there are some limitations about uncertainties of vibration-based damage detection method which can not locate and specify damage in the structure. Therefore, the strain gauge-based measurement should be approached to go beyond the limitation of vibration-based method. Reinforced concrete is one of the most notable material which is widely adopted to construct important structure such as bridges, buildings and sub-ordered structures. Because reinforced concrete structure is non homogeneous material combined between steel-reinforcement and concrete. A complex structure will be performed on the structure. It is very interesting to identify damages in a reinforced concrete structure. Moreover, in the real experiment, there are many experimental problems such as an uncertainty of materials, boundary condition, noise measurement effect and uncertainty of construction which are directly affected damage detection method. For Kurata et al. (2013) and X.Li et al. (2016) studies, the influence coefficient matrix is generated by calculation which might have significant differences from the actual reinforced concrete structure. Therefore, the actual decoupling damage index might improve structural health monitoring. This research uses the damage detection index which are Damage Index (DI) and Decoupling Damage Index (DDI) proposed by Kurata et al. (2013) and X.Li et al. (2016). The study is conducted both a numerical modeling work and an experimental work to perform damage identification method on a reinforced concrete structure. The results from numerical model will be compared with the results from an experimental work. |
