| 摘 要： | 通过1∶150比例的刚性模型风洞试验和数值模拟对单跨空冷结构A型支架、挡风墙和管柱的风载体型系数取值进行研究。分析了风向角、周边建筑物、风机等因素对结构风载体型系数的影响规律，确定最不利工况，并将试验结果与数值模拟结果进行对比分析，结果表明二者吻合较好。最后给出了单跨空冷支架结构体系风荷载体型系数的取值建议，可为工程设计提供参考。 |

| Abstract： | In this paper, through 1∶150 rigid model wind tunnel test and numerical simulation, the wind load type coefficient of A type structure, wind-break wall and pipe column in single-span air-cooled support structure was studied. The effects of fans, surrounding structure and wind direction angle on wind load type coefficient of the structure were analyzed, and the most unfavourable conditions were determined. Through comparison of the test results with the numerical simulation results, it was found that they agreed well with each other. Finally, the recommended values of wind load type coefficient of single-span air-cooled support structure was given, which provided a new basis for the structural design. |
