Taking the bending test of prestressed concrete beam as an example,this paper summarizes the preparation method of optical fiber sensing steel strand and concrete beam,reasonably lays out the measurement points according to the design requirements,and carries out stress loss analysis,bending performance analysis and construction process analysis on the test results,and the results show that the practicability of the prestressed optical fiber sensing steel strand in the test is good,in order to provide an effective reference for the detection of concrete structures.
