This present study investigated interference effects of local peak pressure on a principal building for various locations of an interfering building for various wind directions. To obtain further information and to explain the interference mechanism for enhanced local peak pressure due to the interfering building, simultaneous pressure measurements and flow visualizations using a dynamic particle image velocimetry (DPIV) system were performed in the wind tunnel of the Shimizu Institute of Technology. Experimental results have been examined and presented of effects of an interfering building and wind direction on local peak pressures. DPIV results have shown that, for an oblique configuration, a strong shear layer generated by the interfering building directly hits the principal building, which increases the momentum over its upper surface, resulting in a high pressure coefficient near the leading edge of its upper surface.
