Abstract

In this paper, a series of wind tunnel experiments were carried out on the rigid model of 5-6 storey residential buildings to study the influence of the location, spacing and wind direction of the buildings on the roof wind pressure of multi-storey residential buildings. The test results show that the maximum average wind pressure and extreme negative wind pressure of a single building occur in the roof ridge area at the corner and both ends of the roof, taking a multi-storey building with length × width × height of 60m×12m×20m as an example. For the buildings with three rows and three columns, when the building is located at the corner, the most unfavorable wind direction is 30°, 210°, and 330°. The most unfavorable extreme value of negative wind pressure is -8.72. The negative wind pressure coefficient of the most unfavorable extreme value of the building roof at the corner position and the middle position of the first row decreased with the length-width ratio and the spacing increased. The negative wind pressure coefficient of the most unfavorable extreme value of the building roof at the edge and middle of the second row did not change significantly with the increase of length-width ratio but increased with the increase of space. In the corner area of the roof, the interference factor of the corner position and the middle position of the first row decreased with the space, while the interference factor of the edge position and the middle position of the second row increased with the space. The variation trend of the middle area of the roof is the same as that of the corner area, but the interference factor is generally small. The interference factor of the wall area is always greater than 1.0.
