Abstract

Most previous papers have reported the overshoot phenomena of wind pressure on a roof body under a condition where a gust attacks in a short-rise-time from a calm condition. This paper describes properties of unsteady wind pressures on a gable roof when a gust attacks in a short-rise-time from a steady wind condition according to experiments using a gust wind tunnel test. It was confirmed that overshoot wind pressure decreases with an increase in the initial wind speed, and the overshoot phenomena of wind pressure can be described by non-dimensional coefficients defined for example by the rise-time of a gust, wind speed or its acceleration.
