DAMAGE IDENTIFICATION METHOD FOR CONTINUOUS BEAM BASED ON SHAPE CHARACTERISTICS OF STRAIN INFLUENCE LINES

This invention entails a damage identification method for continuous beam based on shape characteristics of strain influence lines to solve the technical problems. The invention is a success when compared the to the prior art. It has the following as its advantages : the technical solution of the present invention is more convenient in calculation, and can improve calculation efficiency and accuracy when calculating multiple units. By using multiple influence lines for collaborative judgment, the sudden change point can be more obvious and can resist clutter interference.
