高硬度エポキシ樹脂塗料を用いた歪検知センサの開発

抄録

When a big earthquake occurs structure engineers proceed to the spot after the earthquake directly and diagnose suffering degree and will examine the right or wrong of the continuation use of the structure and repair or reinforcement method and need the considerable days till an examination result appears. Therefore the authors have developed the strain detective sensor using hard epoxy based paint for the purpose of anyone putting the sensor which could judge the soundness of the structure members to practical use in simple and easy cheapness after an earthquake than the conventional monitoring system. This sensor can detect the experienced strain based on crack patterns of the paint by observation, leading to drastically reduced cost compared with other sensors such as using strain gauges. In this study, we investigated strain-detection performance in case of the strain history by compression and tension. And the goal of this study was the quantification of the crack properties of the paint.
