Abstract

This paper presents timely varying aerodynamic responses of plate-like structures due torasdom gusts. The aerodynamic admittance or the dynamic lift functions for a few typicalstructural sections, which are considered indispensable in determination of aerodynamic forcesdue to fluctuation of wind velocities in lateral and longitudinal directions, are examinedby use of wind tunnel tests and are compared with the Sears function and the Horlockfunction for thin plate. Based on these aerodynamic lift function, aerodanamic lift function, aerodynamic responses of thin airfoil (NACA-0012) and of long-spanned suspension bridgeare numerically calculated, the results of which indicate a fairly good agreement with theexperimental results.
