Aiming at problem of integral fatigue of cantilever roof structure under wind load,the fatigue coefficients analyses of cantilever structure have been finished with fatigue damage index D in Miner linear cumulative under wind loads based on fatigue life analysis process.

针对风荷载下悬臂挑蓬产生整体疲劳的问题,采用基于总寿命法的疲劳寿命分析流程,由线性Miner累积损伤理论计算疲劳损伤指数D,进行了风荷载下疲劳参数的分析。

A typical cantilevered arc roof model is first established.
