This paper described the characteristics of the peak wind pressure on the wall of high rise buildings on the basis of wind tunnel tests. The experimental models were reproduced from the balconies of actual buildings, in addition to the models without balconies. The building types were regarded as the square prism, oblong plan prism, corner cutting model and corner cut off model. It was noticed how the characters of peak wind pressure coefficient were affected by building shape and roughness on wall. The main results are as follows. The negative peak wind pressure coefficients on the balcony models are smaller almost allover the surface than the model without balconies. On the model without a balcony, the negative peak wind pressure coefficients increased sharply at short evaluation time less than 1.0sec. On the other hand, the coefficients on the balcony model increased more moderately than the models without balconies. On corner cut off model and corner cutting model, they are also reduced by the balconies, in addition to corner cutting effect, except at top corner.
