Numerical Simulations of Wind-induced Mean Interference Effects between Two Low-rise Buildings with Gable Roof

Abstract

In this study, numerical computations for wind pressure of low-rise buildings were conducted in order to investigate wind-induced mean interference effects between the buildings. The primary purpose is to make clear the characteristics of wind pressure distribution on low-rise gable roof building considering interference effects, so as to put forward practical wind-resistant design method and measures. Various ranges of arrangement modes, arrangement distances and wind direction angles were considered based on the numerical simulation method which was verified by wind tunnel test. Results showed that there are the most obvious wind-induced mean interference effects on cornice of interfered building for two same low-rise building. As for the arrangement of low-rise buildings, the tandem arrangement is largest, followed by staggered arrangement and less is parallel arrangement.
