摘 要：采用ANSYS有限元分析软件对该节点建立三维有限元模型，进行了静力分析，以得到该类结构体系在静力荷载作用下的受力性能。结果表明：支座底板下加劲肋下部的加强环能有效降低节点区的应力幅值，节点最大应力发生在加劲肋下部的加强环与下柱相交处，并满足强度要求。

Analysis and research of transmission tower upper and lower column joints based on finite element solution

Abstract： In this paper， a three-dimensional finite element model of the joint is established by using ANSYS finite element analysis software， and the static analysis is carried out. The results show that the reinforcement ring at the lower part of the stiffener under the base plate of the support can effectively reduce the stress amplitude in the joint area the maximum stress of the joint occurs at the intersection of the stiffener ring and the lower column， which meets the strength requirements.
