FBG센서를 이용한 반복하중을 받는 RC보의 계측 시스템 개발
Development of Measuring Data System of Reinforced Concrete Beam Under Cyclic Loading Using Fiber Bragg Grating Sensors
- 발행 : 2005.04.01
초록
In this study, strain measurement and its applicability to estimated deflection curve using fiber bragg grating sensors was conducted. For this purpose, reinforced concrete beams were made and sensors were attached both on the surface of the beams and inside steel. Two types of sensors were used to detect strain on the beams and steel : fiber bragg grating sensors, electric resistance strain sensors. So fatigue test is done with measuring strain of specimen. In addition, this experiments estimates the optimum deflection curve that converts strain curve data measured by FBG sensors into deflection.
