| Research Abstract |
This study investigated the low cycle fatigue failure mechanism of the concrete-filled steel members and verified the fatigue strength improvement methods. The low cycle fatigue tests revealed that cracks were initiated from the base joints of the specimen in the early stage of loading, meaning that the low cycle fatigue can be a final failure mode of the concrete-filled members. Besides, it was indicated that the weld toe treatment techniques can improve the low cycle fatigue strength of the steel members.
