摘要
以某火车站无站台柱雨蓬改造工程为例,通过风洞模拟实验对雨蓬结构的平均风荷载规律进行了研究。讨论了在无周围建筑物影响和典型风向角下,各雨蓬单元的平均风压分布特点,特别对各雨蓬单元之间的风荷载相互干扰现象和机理进行了探讨和分析。结果表明,由于雨蓬单元间的相互干扰,各单元平均风荷载有很大的差别。有关结果可以为类似工程的平均风荷载设计提供指导和参考。
Wind tunnel simulations of wind loading on non-platform-prop canopy of a railway station were conducted. The time-mean averaged wind pressures on the canopy elements under the typical wind directions with no surroundings are taken into account. The interaction of the wind loads on different canopy dements is invested by analyzing the results of averaged wind pressures by experiment methods. It indicates that the interaction between the platform canopies will bring a great difference wind load to the platform canopies. Because of the intercormnunity of all the station, it is worth for similar projects.
