摘要：

Intercomparison experiments with electrical strain gages and optical fibre Bragg strain sensors were performed in both, tensile strain and bending configurations for 14 FBG sensors at room temperature. In a total of 53 quasi-static load tests the strain sensitivities of the FBG sensors were found to be reproducible in the order of 0.5%. The FBG strain sensors showed a mean strain sensitivity of k = 0.792 +/- 0.016, employing the electrical strain gages as reference strain sensors.
