(1 Composite Design Division, China Electronics Engineering Design Institute, Beijing 100840, China; 2 Department of Aseismic Engineering, CABR, Beijing 100013, China)Abstract: Aimed to the distribution of the wind pressure of the high-rise building cluster, the numerical architectural wind tunnel method was used to simulate the wind field of the high-rise building cluster in Xiamen. On the basis of the results, some basic characteristics of the mean wind effect of the high-rise building cluster are concluded. The results of the numerical simulation showed that the high-rise building at the upriver of the wind field has some shielding effect to the high-rise building at the downriver of the wind field, the narrow slot effect will generate when the space between the buildings is too small, and the mean wind pressure at the windward side of the building at the outer of the building cluster is more bigger. The design advices are concluded.
Keywords: high-rise building cluster; numerical architectural wind tunnel; wind load; wind field
