Interference Effect between High-Rise Buildings on Local Peak Pressure by Wind Tunnel Test

Abstract

This research is to study the effect of neighboring buildings in different arrangements on the wind load coefficient of the main building by testing in a wind tunnel using the Local Pressure Measurement method. The wind load coefficients of the main building without adjacent buildings (single building) were compared with the main building that was obscured from neighboring buildings at various distances and presented in the form of wind disturbance factor values. (Interference Factor) in the main building with neighboring buildings at the specified location. The results of the study showed that the wind load coefficients of the main building with neighboring buildings in the oblique manner result in higher maximum suction coefficients than those with neighboring buildings in the same line. The interference effects between the two tall buildings for the maximum pressure coefficients and the maximum suction coefficients at each measurement point of the main building with adjacent buildings are presented and discussed.
