摘　　要：利用有限元分析软件ANSYS建立了一个330KV输电塔架的桁梁混合有限元模型,对其进行极限承载力的分析,描述结构在超载下的破坏过程,得出了结构的极限承载力,这些为塔架结构的可靠性分析和维修加固提供了依据。In this paper,using the general-purpose finite element program ANSYS, it is established a mix model consisted of bar and beam column elements for a 330kv transmission tower.Then the ultimate bearing capacity analysis are carryed out, it is describled the destruction process of the sructure in case of overloading and gained the ultimate bearing capacity of the transmission tower. The results provide a theoretical foundation for the reliability analysis and reinforcement of transmission tower.
