Peak pressure effects on a high-rise building influenced by a mid-rise building
conference paper
Pressure measurements on the surfaces of a high-rise building model with height
h = 0.48 m and width b = 0.12 m were performed in a boundary layer wind tunnel. Experiments
were carried out for an isolated model and for three configurations with an interfering half-height
building model. The effects of the interfering building to the minimum peak pressures on the reference
model were determined. The influence of the separation distance and the shape of the interfering
building (square and circular plan form) were investigated. For the smallest separation
distance, S = 0.5b, the composition of the minimum peak pressures was studied in more detail by
assessment of the mean and standard deviation pressure coefficient. This study shows that the
magnitude of local minimum peak pressure increases with approximately 25-35% on two facades
of the high-rise model. In the top corner of the façade on the side a reduction is observed of 20-
40%, depending on the shape of the interfering model.
