Basic Study on Multi-Bay Horn-Shaped Membrane Roof

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.

Performance and Measurement Devices for Membrane Buildings in Civil Engineering: A Review

“…In the case of oval-shaped arch-supported structures, the influence of parameters on the windward side outweighed the influence on the leeward side. In real-world engineering applications, such as multi-bay horn-shaped membrane structures consisting of various identical unit systems, Nagai et al [71] discovered that the wind load coefficients of the stand-alone model could practically fulfill the research of open structures. In contrast, enclosed structures need to be examined by adopting the multi-bay model.…”
