영문 초록

As material needs have been increasing with recent economic growth, it is a current tendency that the magnitude of load applied to structure has been rising. With improved technique of product materials, steel and concrete have been stranger than ever so the danger of fatigue damage increases as permanent action of repeated loads. In case of deformed steel bars widely used in reinforced concrete structure, when they are product in factory, there will exist same parts connecting the steels. Such connections are easy to be weakened by permant action of repeated loads. It is a real condition in Korea that there is lack of research of it. As a result of estimating fatigue characteristic of Pressure Welded joints with the steels that are oftenly used and producted in domestic it is showed that there are no remarkable difference in fatigue strength. Because there is no detail which is refered in Civil Specification, this paper will be the basic data being added in later Specification.
