해양구조물의 K-Joint 피로연구
Fatigue Study of K-Joints for Offshore Structures
초록
The paper describes a test program on welded K-joints fabricated from circular hollow section brace members and chords made with API 2W 50 grade steel produced by POSCO. The K-joints were tested for three loading conditions at RIST. The specimens were tested in a reaction frame that allowed vertical uniform loading to the structure. From the tests, the crack initiation and development were observed and the fatigue failure could be predicted. The results were also compared with the provided S-N curves by DnV.
