Abstract
Wind pressure loads for mono-sloped roof buildings have been determined experimentally by testing a variety of models exposed to a simulated atmospheric boundary layer flow over an open country terrain. Geometrical parameters examined include the effect of height (3.6–12.2 m), width (12.2–24.4 m) and roof slope (1:12–4:12) on both local and area-averaged pressures measured for a variety of wind directions. The effect of scaling has also been examined by testing similar models of different size in the wind tunnel. Experimental data indicate that both mean and instanteneous peak wind pressures are higher than those found previously for buildings with gabled roofs. This is particularly true of roof corners and narrow buildings. Some trend with the height has also been found for corner points. This paper presents comparisons with previous studies and codes.
