摘要
Abstract
In response to the load-bearing characteristics of rigid and flexible flange joints in single steel tube lightning rods and based on an analysis of a collapse accident,this study proposes four new types of flange joints.These designs incorporate a core pipe to enhance the joint's bending stiffness.The static load performance and patterns of stress distribution of the new joints and a traditional rigid flange joint were analyzed using ABAQUS finite element software.The results showed that the new flange joints exhibited bearing capacity and flexural stiffness comparable to those of the traditional rigid joint.Moreover,the new designs demonstrated a significant improvement in mitigating stress concentration.This enhancement is beneficial for improving the fatigue performance of the lightning rod flange joints.关键词
