Abstract

Two elementary responses of bridge aerodynamics, namely unit-step (indi-cial) and unit-impulse responses via which the convolution integrals are constructed, are systematically reviewed in this paper. Both direct and indirect identification schemes for these two elementary responses are discussed. The comparison of the indicial and rational function approximations, which are utilized in the indirect identification schemes, is emphasized by presenting the physical significance of various steps of the mathematical deductions. A numerical example of a long-span bridge is given to show the accuracy of approximation of these two indirect identification schemes.
