Three-Dimensional Dynamic Characteristics Analysis of Large Span Cable-Stayed Aqueduct

The cable-stayed aqueduct has become a new form of aqueduct after the beam and arched aqueducts. But the study focused on the dynamic characteristics of cable-stayed aqueducts is not enough. Based on the structure of cable-stayed aqueduct, the inner water is considered as added mass. The three-dimensional finite element model of fluid and the cable-stayed aqueduct is established to analyze the dynamic characteristics of aqueduct in different conditions. The results show that the dried modes and wet modes are analogous, but the natural frequencies of vibration are obviously different. The natural characteristics of vibration are three-dimensional and coupling with torsion mode. The cables have no effect on the fundamental frequency of lateral bending mode of vibration though they enhance vertical restraints to the aqueduct body.
