Abstract
The influence of different damping coefficients on the dynamic response of a concrete-filled steel tubular (CFST) arch bridge is analyzed using the finite element method (FEM). The obtained results show that the effect of different values and different types of damping coefficients on dynamic response is great and changes nonlinearly. The chapter also explains that the damping change of main supporting elements is more essential than that of other members; therefore, the advanced damping mechanism of CFST material and structures should be studied to select the appropriate damping type and value for precise analysis and design. In the chapter, the dynamic response of a half-through CFST arch bridge is analyzed with harmonic response and time-history method, and the influence of different types and different values of damping coefficients on the response of CFST arch bridges is discussed.
