Wind pressure coefficients on exterior wall elements of tall building.

Reports measurements of wind pressure distributions on a model of tall building made in a turbulent wind tunnel with a velocity gradient. The wind pressure distributions in a constant uniform velocity field were also measured and the differences in thepatterns of pressure distributions due to the effects of velocity gradient were observed at lower part of the model.< Also describes measurement of natural wind pressures and glass strains on a 36 storey office building. Finds inter alia considerably large pressure fluctuations of short gusts although average pressures are small.
