摘　　要：研究了变电构架中钢管刚性法兰盘连接的抗拉受力性能,应用大型有限元软件ANSYS进行了非线性数值分析,揭示了刚性法兰盘在拉弯力作用下的受力特点,将有限元计算结果与《架空送电线路杆塔结构设计技术规定》(DL/T5154-2002)计算结果进行对比分析,为修编《架空送电线路杆塔结构设计技术规定》刚性法兰节点连接章节提供参考依据。The function of flange joint with stiffening rib in powertransformed frames under tension is studiedAnd an nonlinear finite element analysis is conducted,by generalpurpose finite program ANSYSThe results show the characteristic of the flange with stiffening rib under tension and bendingThese results are compared with those of “Technical Regulation of Design for Towers and Pole Structure of Overhead Transmission Line”(DL/T 51542002) and be referential to mending the pertinent clauses of the code
