Simulation Study of Electromagnetic Standing Wave Method for Pre-stress Detection of Steel Strands

Abstract

With the widespread application of pre-stressed technology, effective pre-stress monitoring has become a key research area in the field of health monitoring, such as bridges. This paper conducts a simulation-based validation study based on the electromagnetic standing wave pre-stress measurement method. Through the analysis of the implementation process and principles of the electromagnetic standing wave measurement method, frequency domain simulations are performed in HFSS software, and then the frequency domain results are imported into ADS for time domain simulations, ultimately verifying the feasibility of the electromagnetic standing wave pre-stress measurement method. Experimental results indicate that the electromagnetic standing wave method can achieve non-destructive and effective monitoring of in-service pre-stressed steel strands.
