摘　　要：输电塔常采用上部单肢角钢主材下部组合双角钢主材的构造型式,在单双角钢过渡节点由于上下主材重心重合必然导致上下靴板形成偏心,规范中尚无对此类节点的设计方法。该文介绍单双角钢过渡节点承载力的研究状况及目前的研究进展,概述其要受力特点、破坏模式,总结单双角钢过渡节点的实验结果和数值模型。最后,对单双角钢过渡节点的承载力研究进行展望。Transmission towers often adopt a structural type in which the upper single-leg angle main material is combined with the lower double-leg angle main material.At the single-double angle transition node,the center of gravity of the upper and lower main materials coincides,which will inevitably lead to eccentricity of the upper and lower gusset plates.There is no design method for such joints in the specification.This paper introduces the research status and current research progress on the bearing capacity of single-double angle transition joints,summarizes its main force characteristics and failure modes,and summarizes the experimental results and numerical models of single-double angle transition joints.Finally,the paper provides an outlook on the future research directions in this field.
