Research Abstract

The unsteady aerodynamic forces acting on a vaulted roof vibrating in the first anti-symmetric mode in a turbulent boundary layer have been investigated by a wind tunnel experiment and CFD analysis. The unsteady aerodynamic force is represented by the aerodynamic stiffness and damping coefficients and given by a function of the reduced frequency. A discussion is made of the application of these coefficients to the dynamic response analysis.
