摘　　要：对温州东海广场工程这一具有较大截面长宽比的复杂高层建筑进行了风荷载数值模拟和风洞试验研究。首先,在工程预研阶段用数值模拟方法计算得到了主要风向角工况下结构表面的平均风荷载分布。然后,参考数值模拟计算结果,引导进行风荷载风洞试验的测点布置方案,进行风洞模拟试验研究。最后,将数值计算结果和风洞试验数据进行了对比,显示数值模拟计算和风洞试验结果两者吻合较好。研究表明,综合采用数值模拟和风洞试验研究,可以较为准确地把握复杂建筑结构的风荷载分布,这种方法有助于提高结构抗风研究的水平。Numerical simulation and wind tunnel test for wind loads of Wenzhou Donghai Plaza were introduced in this paper.Firstly,the mean pressure distributions in several main wind attacks were calculated through constructing appropriate CFD numerical models.Secondly,referring to the results of numerical predictions,the scheme of the subsequent wind tunnel test was optimized.Finally,comparative results of numerical predictions and the data of the wind tunnel test show good agreement.In this study,it is indicated that the combined numerical simulation and the wind tunnel test can be more reasonable than the traditional wind tunnel test method.
