Characteristic of Wind Pressure for Screen Standing on Rooftop

Abstract

This paper describes characteristic of wind pressure for screen standing on rooftop. The blindfold screen is often attached to the outside perimeter of building. In this study, wind tunnel tests were performed to investigate difference in peak wind force coefficient obtained from backside pressure of the screen and rooftop pressure, and the characteristics of backside pressure of the screen. As a result, we experimentally clarified difference occurs in the peak wind force coefficients obtained from backside pressure of the screen and rooftop pressure, because backside pressure of the screen changes to vertical direction depending on wind direction. However, there was no change in the value of the maximum peak wind force coefficients in the all wind direction.
