Abstract

The paper describes experiments made on model buildings, of different shapes and under many varying conditions of air stream
pressure, in the wind tunnel of the aerodynamic laboratory at the University of Melbourne.
The experiments were made in an endeavour to ascertain the pressure and the distribution of pressure, caused by an air stream acting on
a building under different conditions, with the object of obtaining design data. For this purpose, the pressure was measured at various positions
on the outside of a model building and compared with the free air stream pressure. These values were plotted, and by a double graphical
integration the mean pressure acting on any face was arrived at. By a process of reduction these pr~~sures were converted to force coefficients,
the forces acting in three mutually perpendicular directions, one of which was the longitudinal axis of the model.
The experiments show that the total force in the wind direction never exceeds that on a flat plate, but may approximate it. However,
the pressures on any individual face, may, under certain conditions of internal pressure caused by openings in the building, be appreciably greater
than for a flat plate.
