Fracture damage identification of pile using element strain energy method based on sensitive modals

摘要：

　　A sensitive identification method for fracture damage identification of pile was established using the rate of change of natural frequency,element modal strain energy method and fracture mechanics theory.According to the structural vibration equation of damaged pile,a structural damage identification equation was deduced which containing modal damage sensitivity factor,fracture injury factor of pile and element modal strain energy change ratio.
