| 摘 要： | 岸桥在脉动风作用下容易产生振动导致动态滑移或倾覆,因此岸桥脉动风荷载的精细化研究极为必要。通过风洞测力试验对岸桥进行风荷载特性分析,得到结构的风荷载统计参数,对比了不同工况下岸桥的平均风荷载以及脉动风荷载,结果发现岸桥的最不利风向角出现在斜风向。同时根据试验的风力系数,拟合出风向角与风力系数的函数关系式,为岸桥结构的抗风设计提供参考。

| Abstract: | Quayside container cranes are usually subjected to dynamic slidingor overturning under the fluctuating wind due to structural vibration.Therefore,the study on the fluctuating wind load is extremely necessary.This paper analyzed the wind load characteristics of cranes by wind tunnel test,and the statistics of wind load were obtained.The mean and RMS wind load of the crane under different conditions were compared.,Finally,the fitting formula of the wind force coefficient with respect to yaw angles were summarized,providing reference for the wind-resistant design of quayside container cranes. |

| Keywords: | container crane wind tunnel fluctuating wind load fitting formula |
