Paper Title:
Fatigue Test and Research on Tubular Joints of Concrete-Filled Steel Tube
  Abstract

For the further study on stress concentration and fatigue property of tubular joints of concrete-filled steel, we designed the fatigue test on tubular joints of concrete-filled steel.Associating with the calculation of finite element, we studied the stress concentration, cracking source of fatigue, and fatigue -related rules including cracking expansion. I did the equivalent calculating under variable amplitude loading. We proposed the criterion of fatigue failure when surface length of penetrated crack is about 3 times as the thickness of the wall. According to the experiment we verified that the tubular joints under the amplitude load this criterion is reasonable, secure and feasible.
