［摘要］河南藝術(shù)中心為建筑體型獨特的集群建筑，風荷載對各單體建筑相互干擾的群體效應(yīng)明顯；藝術(shù)墻位于建筑群體中央，其獨特的喇叭口造型產(chǎn)生聚風效應(yīng)。依據(jù)風洞試驗結(jié)果，重點對藝術(shù)墻典型部位的風荷載體型系數(shù)進行歸納對比分析，總結(jié)群體效應(yīng)中遮擋、峽谷效應(yīng)、漩渦作用對體型系數(shù)的影響規(guī)律，為類似工程提供參考。

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
