Paper Title:
Finite Element Analysis of Thermal Stress on FBG-GFRP
  Abstract

This paper investigates the influence of thermal stress on FBG embedded in GFRP bar by the finite element analysis and the calibration test. The temperature sensitivity coefficient of smart FBG-GFRP analyzed by FEM is 17.42 pm/°C, which is about 1.65-fold of bare FBG’s namely 10.53 pm/°C. And the coefficient got by calibration test is 17.6 pm/°C. The result shows that the influence of thermal on FBG is very big, after encapsulated and before used in structure, the temperature sensitivity coefficient of FBG must be calibrated.
