Notes:
In recent years, embedded fibre-optic sensors as structural health monitoring deviceshave been widely used in both civil and aerospace engineering applications. Their small physicalsize and ability to immunize electromagnetic interference make them ideal sensing devices, whichprovide highly accurate and reliable strain and temperature measurements for structures. This paperpresents a new designed temperature-compensated fibre-optic Bragg grating (TCS) strain sensor forimbedding into cement-based materials to measure their mechanical and thermal strainsindividually or simultaneously. However, the residual stress generated due to the constrainedboundary of a steel tube that is used to protect the sensor, will influence the accuracy ofmeasurement. Therefore, a theoretical model that is used to estimate this stress at differenttemperature conditions is discussed
