［摘要］河南艺术中心为建筑体型独特的集群建筑，风荷载对各单体建筑相互干扰的群体效应明显；艺术墙位于建筑群体中央，其独特的喇叭口造型产生聚风效应。依据风洞试验结果，重点对艺术墙典型部位的风荷载体型系数进行归纳对比分析，总结群体效应中遮挡、峡谷效应、漩涡作用对体型系数的影响规律，为类似工程提供参考。

Abstract:Henan Provincial Art Centre has a unique architectural shape with the group buildings, which creates an apparent mutual interference from each specific building due to wind group effect. The art wall, situated in the middle of group buildings, owns a unique shape of “horn mouth" that generates wind gathering effect. According to wind tunnel test, the dynamic shape factors on the typical locations of the art wall are mainly listed and compared, in addition that it is summarized that barrier, canyon effect, and spiral vortex action have an impact on dynamic shape factor in group effect, which provides the references to other similar projects.

Keywords:dynamic shape factor; wind tunnel test; group effect; interference coefficient
