Abstract : The fiber Bragg grating strain sensors were located in the reinforced concrete beam in order to monitor its stress-strain value for the verification on the precision and accuracy of the fiber Bragg grating sensors measure. The strain's monitored results in testing tallied with the results from the electric resistance strain gauges and with the theoretical calculation. Afterwards, the fiber Bragg grating sensors were applied successfully in monitoring the stress for the important components of the super high-rise building. The embedded technology of the fiber Bragg grating sensors and the protection method for the sensing system, both of which were suitable for the site construction characteristic of the civil engineering, were explored. The stress variation of the components was monitored in the construction. The engineering application indicated that the optical fiber Bragg grating was a reliable mean to actualize the long-term structure health monitoring-
