Abstract:Based on the pressure measurement tests of wind tunnel experiments, this paper discussed the impacts of different types of terrain and surrounding interference for peak wind pressure on the high-rise buildings. The results show that different types of terrain have a great impact on the peak pressures of high-rise buildings. When the surrounding environment of high-rise buildings remains unchanged, the peak pressure coefficients of different types of terrain are followed by B, C and D from large to small in most cases. The peak pressure impact of high-rise buildings is not only related to the relative position of the surrounding buildings, but also to the type of terrain a high-rise building at the time. For example, if the south facade is the wind surface and interfers buildings E and F located diagonally in front of the south facade, it performs a shielding effect. In this case, the vast majority of the peak pressure coefficients obtained in the terrain category of B, C and D are reduced differently in the vast majority of test points with a maximum decrease of 43%, 37% and 46% respectively.
