Abstract

Already the authors have reported that wind pressure on many local points of a gable roof body under a short-time rise gust wind became much bigger than in a steady flow. This is called the overshoot of wind pressure. This paper focused on the direction of a gusty wind against a gable roof body. We investigated properties of wind pressure on a gable roof body under a short-rise-time gust acting to its gable wall by wind tunnel test. We found that the peak wind pressure coefficients of the roof under a gust to the flat wall which runs parallel to the roof’s ridge became bigger than under a gust to the gable end wall in the same non-dimensional rise time of gusty wind.
