چکیده انگلیسی
This paper addresses the interference effects of high-rise building caused by either an upstream or downstream adjacent building. During the study, aeroelastic vibration tests and high-frequency force balance tests are conducted for two identical square prism models of buildings with an aspect ratio of 8 in a turbulent boundary layer flow. Later, critical locations for interfering buildings are identified by examining interfered force spectral characteristics and various patterns of response trajectories. Finally, an idealized 2D numerical simulation of CFD is tried for the simulations of some critical cases. Although the absolute values from CFD results cannot be perfectly compared with the experimental results, the simulated vorticity movement generated from the existence of both buildings provides an intuitive way for the enhancement of the downstream interference mechanism.
