Abstract

This paper carried out the early age autogenous shrinkage research of large scaled HPC column specimens by embedded Fiber Bragg-Grating (FBG) strain sensor. Temperature compensation for FBG strain sensor by thermocouple was also attempted.

이 논문은 매립형 FBG 스트레인 센서를 이용하여 고성능콘크리트 시험체의 초기재령시 자기수축에 관하여 연구하였다. Thermocouple 에 의한 FBG 스트레인 센서의 온도보정도 이 논문에서 수행했다. HPC 자기수축량에 대한 배근영향, 크기효과, 온도효과 역시 분석했다.
