Abstract
Added mass has significant effect on wind-induced vibration of membrane structures. At present, research on the added mass of membrane structures is still limited. Li, et al tested the vibration of circular flat membrane in still air with varying air pressures, and a simplified added mass model based on the vibration mode shapes of flat membranes was proposed. However, the research work just focused mainly on flat membrane structures. The purpose of this paper was to investigate the added mass of curved membranes in still air and verify the suitability of the proposed simplified added-mass model for curved membranes.
