Dynamic Characteristic and Damage Diagnosis of Inclined Column Ancient Bridge
Make simulation analysis and damage diagnosis for inclined column ancient bridge based on the finite element modeling and on-site dynamics experiment. Establish the finite element models of the inclined support bridge (YuQing Bridge) and the upright support bridge (a reference bridge), respectively, and make modal analysis and seismic Time-History analysis. Finally, comparing the calculation results with pulsation experiment, it gets that the dynamic characteristics of this inclined support bridge are superior to those of upright support bridge. And the torsional rigidity damages of the inclined support bridge have already existed.
