WIND-FORCE COEFFICIENTS OF THE HORN-SHAPED MEMBRANE ROOF UNDER THE UNIFORM-FLOW

Wind load is the most dominant load for light-weight structures such as membrane roofs. Particularly since the horn-shaped (conic) membrane roof has a complicated shape and is generally composed of several numbers of horn-units, the basic data for the wind-force coefficient has not been reported.In this paper, the authors focus on the wind-force coefficients under the uniform-flow. The authors conducted many types of wind-tunnel tests and clarify the aerodynamic characteristics under several conditions.
