Wind Force Coefficients for Designing Framed Membrane Structures of Open Type

Abstract

Wind force coefficients on a semi-open type structure are proposed on the basis of the result of a wind tunnel experiment. Two cases of gable-wall opening are investigated; only one gable wall is open in a case, while both gable walls are open in other case. Closed-type model is also tested for a comparative purpose. The wind pressures are measured both on the external and internal surfaces in a turbulent boundary layer. Based on the results, we propose the structural wind force coefficients for the main wind force resisting system using the LRC method, in while focus is on the bending moment involved in the columns as the load effect.
