| Abstract: | The static and fatigue tests of12 specimens of suspender, which connects the crane rails tothe space grids joints, are presented. BY analyzing the fatigue failure modes of susponder,the fatiguefracture of the high strength bolts is a main failure mode of the suspender spocimen. Based on theanalysis of the data of fatigue experiment by statistics,the fatigue curves of the high strength bolts insuspenders and their fatigue strength relationship are put forward. Some recommendations for thefatigue design of suspender are suggested. |
