Abstract : A general discussion of the various techniques used to measure the oscillating lift coefficients of wind-induced vibrations of circular cylinders is presented. The discussion is summarized with a brief outline of the various categories of research efforts being conducted on fluid-induced vibrations. Each category is referenced to an appropriate group of papers which exist in the literature. A simple method for determining the oscillating lift coefficient for the wind-induced vibration of a circular cylinder is developed and applied to a typical problem where the longitudinal axis of the cylinder is skewed relative to the direction of the oncoming flow.
