Wind loadings on the low-rise buildings around the hillside in atmospheric boundary layer

A series of wind tunnel aerodynamic experiments were conducted to investigate the wind loads on the low-rise buildings located around the hillside. The result shown, the steep roof slope may cause a separation bubble at the edge and the small separation shear layer reattached the roof just near the edge due to the steep slope of roof at the uphill side. At the downhill side, the mean pressures of the building with gently slope roof to be positive for most of them. The building seems to be covered by the hill separation bubble, and the approaching flow with negative inclination acting on the buildings. The surface pressures of low-rise buildings may not reflect the local shear layer behaviors, but they shown the acting results of the wake of the hill. The fluctuating pressures distribution at low-rise buildings located at hillside would slightly less than the ones without hill.
