Mutual interference effects between two high-rise building models with different shapes on local peak pressure coefficients

This study investigates the interference effects between two high-rise buildings with different shapes by wind tunnel experiments, focusing on local peak pressure coefficients. To examine the interference effects for local peak pressures in detail, interference factors for maximum positive and minimum negative peak pressures at each measurement point "i" of the principal building for all wind directions are presented and discussed. The results show that these effects greatly depend on building shapes and wind directions. They also show that special care should be taken with cladding design at the vertical edges, especially corners of buildings, since the smallest minimum peak pressure on a building face might be 40% larger than in the isolated condition.
