Abstract
Wind loading is the most dominant load for light-weight structures such as membrane roofs. Since the multi-bay horn-shaped membrane roof has a complicated shape and is composed of several horn-units depending on the building type, basic data for the wind-force coefficient has not been reported yet. On the other hand, the multi-bay horn-shaped membrane roof is usually designed using the structural behavior of a one-unit system. Furthermore, the authors consider that the design method must be changed not only according to size and building type but also supporting systems. From the view of these problems, in this paper, the wind-force coefficients for design and analysis are clarified by the wind-tunnel test, and a design method considering the influence of supporting systems under wind loading is proposed.
