| Abstract: | The influence of thermal stress on the temperature sensitivity of fiber Bragg grating-glass fiber reinforce polymer(FBG-GFRP) bars is studied by three methods,namely,direct experimental calibration method,stress analysis(finite element analysis) method and the method of apparent temperature sensitivity coefficient.In comparison with the other two methods,fewer parameters are required and the calculation is simple in the method of apparent temperature sensitivity coefficient,while the analytical error is lim... |
