为研究复合材料输电杆塔的节点构造方案，对比分析了预埋金属件、插接以及金属套筒三种复合材料节点连接方案，确定了金属套筒方案为复合材料输电杆塔节点连接方式。利用ANSYS 有限元程序，并结合真型试验的结果，从节点可靠性、变形控制等方面对金属套筒方案进行优化。研究了节点刚度与变形协调性、局部变形与节点失效的关系，从而为工程应用提供参考。探讨了复合材料杆塔横担与塔身及金具的连接方案，并且进行了横担连接真型试验。

To research the joint construction of FRP（fiber reinforced plastics）towers, three alternative schemes, including embedded metal part, plug and metal sleeve, are compared and the metal sleeve scheme is selected. The selected metal sleeve scheme is optimized in terms of node reliability and deformation control through ANSYS simulation and full-scale testing. The paper studies the relationship between joint stiffness and deformation coordination and that between local deformation and joint failure, and explores the joint scheme between FRP tower’s cross arm and tower body as well as hardware. Full-scale testing is also conducted for the cross arm joint.
