Impact Studies on the Setting Styles of Stiffened Board to the Ultimate Strength of Tubular K-joints

摘要

This study taking the transmission steel pipe tower in the actual project as research background analyzes the mechanical property of stiffened steel tube K-joint. However, stiffened steel tube K-joint is not in the range of the code for design of steel structures GB50017-2003 of China. The corresponding solid models of finite element including K-joint in code of China and stiffened K-joint in actual project are set up to study the plastic distribution on post pipe and the influence of different setting styles of stiffened board to ultimate bearing capacity of K-joints. It was finally known that the stiffened K-joint has better mechanical property than unstiffened K-joint.
