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.
