摘要
The present invention relates to a method for estimating the tendon damage of a PSC bridge using an autoencoder, and the present invention provides acceleration, displacement, strain, etc. representing the small behavior of a PSC bridge that can be obtained through a SHM system in order to grasp the risk of the bridge in real time. A first step of collecting bridge measurement data during a set period so as to estimate the damage of the Tendon using the bridge measurement data of; A second step of generating a tendon damage estimation model capable of restoring only'non-damaged state' data by performing auto-encoder learning by considering the bridge measurement data as'non-damaged state' data; When the bridge measurement data measured in real time from the bridge measurement unit is input, a third step of determining whether or not the bridge tendon is damaged by determining whether it is'non-damaged' data through the Tendon damage estimation model; PSC using an autoencoder including It provides a method for estimating the tendon damage of a bridge.
