Simulation Analysis of K Node on UHV Transmission Tubular Tower

Abstract:

Layout for K node of steel tubular UHV transmission tower is analyzed in systematic and all-sided with finite element calculation in this paper. The recommendation is that as no applicable formula is available at present, existing specification can still be used for calculation but with a safety margin of more than 10%. K node connected in intersecting welding manner with appropriate stiffening rib will improve the stress, gender more uniformed stress distribution, and effectively reduce stress concentration. Welding connection features smaller displacement and maximum stress and more uniformed stress distribution relative to plug-in connection, therefore it is recommended to be used for K node with slope.
