| Abstract: | Vibration Characteristics test was carried on a model of one three-spanned prestressed concrete(PC)shew continuous box girders,which was designed in Jing Hu high speed railway of China.We discuss the difference between the results of test and 3D FEM analysis with two cases of orthogonality and shew,and explore the dynamic properties of skew box girders. |
