对钢管塔带连接板的K型结点进行了有限元分析,并探讨了基于1/4环型加强板主管轴力对极限承载力的影响,表明轴力对结点承载力的影响是不可忽略的;通过数据拟合,提出了在有轴力作用的情况下,1/4环型加强板的K型结点极限承载力的轴力影响折减系数KN;为K型钢管结点极限承载力的设计提供依据。
The finite element analysis of the K-type joint of the steel pipe-tower web and the influence of the axial force on the ultimate bearing capacity of the steel pipe-tower-type connecting plate are discussed. The results show that the influence of axial force on the bearing capacity of the joint is not Neglected. According to the data fitting, the axial reduction factor KN of the ultimate bearing capacity of the K-type joint of 1/4-ring stiffener under the condition of axial force is proposed. Bearing capacity of the design basis.
