Title:
METHOD AND APPARATUS FOR PREDICTING SERVICE LIFE OF STEEL BOX GIRDER, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/155349
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the field of data processing, and provide a method and apparatus for predicting the service life of a steel box girder, a device, and a medium. The method comprises: determining multiple stress amplitude ranges according to multiple preset discrete stress amplitudes; determining multiple dynamic S-N curves according to the multiple discrete stress amplitudes and a decay coefficient of each stress amplitude range, the decay coefficient of each stress amplitude range being used for representing the degradation degree of the material performance of the steel box girder in each stress amplitude range relative to the material performance of the steel box girder in the previous stress amplitude range; and predicting the service life of the steel box girder according to the multiple dynamic S-N curves, multiple monitoring stress amplitudes of the steel box girder, and multiple monitoring cycle times in one-to-one correspondence with the multiple monitoring stress amplitudes, the multiple monitoring stress amplitudes being within the multiple stress amplitude ranges. The embodiments of the present application solve the problem in the prior art of the limitation of predicting the service life of the steel box girder, and achieve the effect of improving the accuracy of predicting the service life of the steel box girder.
