The main purpose of this study is to understand fatigue characteristics with various shapes of welding connections which are the most weak point of steel structures. Theoretically, the characteristics of fatigue behavior and crack, propagation are reviewf:d, and factors affect fatigue strength of welding connectioi: are described. And, 5-N curves are made by the result of fatigue test with various test specimens. For the test, the stress range was arranged by the result. of tension test of base metals.
