Research on Dynamic Properties of Concrete Steel Tubular Arch Bridge Based on ANSYS

Abstract:

Based on ANSYS for modal analysis of bridges, the basic steps includes: building up the FEM model, applying the load and solving the model, expanding the mode, observing the results and so on. Taking the Friendship Avenue Arch Bridge as an example, the building procedures of FEM model were described from the definition of member section, element selection, and the determination of relevant attributes. At last, the dynamic characteristics of the bridge were analyzed based on ANSYS. The results showed that the first 10th order vibration frequencies of the Friendship Avenue Arch Bridge ranged from 1.3Hz to 3.1Hz, and the more order modes should be considered when calculated the dynamic response based on the mode superposition method.
