Abstract: Very large scale cable domes have been built using prestressed, high strength steel cable or strand, steel tube columns and a lightweight fiberglass skin. Geiger Engineers Florida Suncoast Dome is geometrically nonlinear and its behavior strongly depends on the level of prestressing. Because of its relative lightness, its prestrain-dependent behavior and geometric nonlinearity, a study of the dynamic behavior of the dome was performed. Specifically a 1|100 scale model of that dome was fabricated and tested both under harmonic excitation and in a wind tunnel. In addition, mathematical models of the domw were defined and analyses performed. This paper describes the physical model and presents preliminaryt results from the wind tunnel study.
