Identification of Mechanical Parameters of Prestressed Box Girder Bridge Based on Falling Weight Deflectometer

Identification of Mechanical Parameters of Prestressed Box Girder Bridge Based on Falling Weight Deflectometer

Traditional damage detection methods of prestressed concrete box girder bridges have low efficiency and cannot quantify the structure’s internal damage. We used an inversion method and a falling weight deflectometer to estimate the mechanical parameters of prestressed box girder bridges. A finite el...
