台风作用下大跨度圆形钢网架储煤场风载荷特性研究

STUDY ON WIND LOAD OF COAL SHED UNDER TYPHOON

为了探究台风作用下大跨度煤场结构风荷载特性,以某火力发电厂圆形钢网架储煤场为工程背景,应用风洞试验模型结合现场研究圆形钢网架储煤场穹顶钢结构的平均风压以及峰值风险分布情况,分析网架波纹板因风作业导致损坏的主要原因,并根据试验结果对煤场网架表面风荷载进行风压分区,为工程设计实践提供参考。

In order to investigate the wind load characteristics of large span coal shed structure under typhoon action,the distribution characteristics of average wind pressure and peak wind pressure of coal shed roof structure were studied by using model wind tunnel test in Guohua Taishan Power Plant,Guangdong Province.According to the test results,the wind pressure zone of coal shed surface wind load is carried out,which provides reference for engineering design practice.
