摘要
The present invention provides a method for estimating the remaining service life of steel structures and methods of monitoring crack growth in the steel structure . ; In the present invention, a potential difference between the measuring area is disposed in a grid pattern and preferably a plurality of terminals for measuring the potential difference between the surface and the steel structure, and applying a current to the region, a plurality of terminals for measuring the potential difference and intermittently or continuously measuring the potential difference with respect to the measurement terminal pair to the two of a pair. FC fingerprint coefficient to calculate the electric field from the resulting potential value. And the relationship between the crack binary value that determines the total amount to the FC by using the test piece simulating the pre-steel structures in the master curve, the master using the curve amount of the crack and to monitor the binary value from the FC measured in steel structures. In addition, placing the test piece, and determined by using a pre-simulation steel structures, and the relationship between the weight load limit value of the number of iterations and FC to the number of iterations in the master curve test body is collapsing, the same measurement terminal pair of steel structures from the master curve reading out the weight load in the time interval t the number of iterations corresponding to the respective values measured with the FC, and the load of each load is estimated by the number of iterations the remaining service life of steel structures.
