Abstract

This study investigated the wind pressure characteristics of an elliptical retractable dome roof with a central opening. Wind tunnel experiments were performed on elliptical dome roofs with varying wall height-to-span ratios (0.1-0.5) and opening ratio of 30%, where the opening ratio was defined as the ratio of the open area of the roof to the total area of the roof. The resulting peak pressure coefficients of the elliptical dome roof were then compared with those of the korean wind load code (KDS 41 10 15) as there are no current peak pressure coefficients for the cladding design code of elliptical dome roofs and open roofs. As a result, the experimental values exceeded the current code.
