摘　　要：为了给工程设计提供参考依据,对钢混组合结构大跨越输电塔中的格构式角钢-钢管混凝土主管和钢管混凝土-钢管相贯节点等关键技术进行了试验研究,获得了格构式角钢-钢管混凝土主管的整体稳定性能、破坏模式和承载力以及钢管混凝土-钢管相贯节点的管壁变形、应力集中系数和承载力数据,并提出了承载力计算方法,可用于类似结构的设计中。In order to provide reference for the design of composite structure power transmission tower, the test study is carried out to investigate key technologies such as the concrete-filled steel tubes with lattice angle, and the concrete-filled steel tubular connection. Yhese investigations produce results on stability, failure mode, and bearing capacity of the concrete-f＇dled steel tube with reinforced lattice angle, as well as the chord-wall deformation, stress concentration factor, and beating capacity of the concrete-filled steel tubular connection. Finally, a beating capacity calculation methodology is proposed, which could be used for the design of similar structures.
