Theoretical Analysis on the Ultimate Bearing Capacity for Steel Tubular Transmission Tower’s Joints with Annular Plate

Article Preview

Abstract:

The aim of this paper is to study the ultimate bearing capacity of steel tubular transmission tower’s joint with annular plate based on the theoretical analysis. A simplified model of annular plate joints was performed to investigate the force distribution of the tube-gusset joints. To obtain the state of stress and ultimate bearing capacity, the annular plate with clamped boundary condition on the inner edges and subjected to diametric loading is employed in this study by the direct integration and thin plate energy principle theory. Experiment and finite element analysis are carried out and the results show that both are the similar.
