| 摘 要： | 采用不同的简化方法，对自升式平台桁架桩腿所受风载荷进行了研究，并使用ZenStab软件建立了4种桁架式桩腿的简化模型，用于计算分析桁架式桩腿所受风载荷，确定简化模型用于计算桁架桩腿风载荷的合理性。计算结果表明，将整个桁架式桩腿截面等效为正三角形或圆形，计算得到桁架桩腿风载荷比较接近实际情况。

| Abstract: | The wind load on the truss leg of jack-up units is studied by different simplified methods. In order to determine the rationality of simplified model, we create four simplified truss leg models by ZenStab software used to calculate and analyze the wind load on truss leg. The calculated results show that the wind load of the truss leg which is simplified to equiva-lent regular triangle or circle section is much close to true condition. |
