Based on the knowledge through the fatigue tests on welded steel joints, this paper investigates the fatigue characteristics of the welded joints widely used in ordinary steel buildings under the wide range of cyclic motions due to seismic and/or wind loads. The authors intend to make most use of the fatigue data in designing super high-rise buildings as well as the buildings in which the plastic yield hinge due to seismic or wind loads in members may be allowed. According to the "Guidelines and Description of Fatigue Design" published by the Japanese Society of Steel Construction (JSSC), the fatigue design is available only for the welded joints widely used in steel buildings. Not so much information on experimental fatigue data has been recently found for the wide-used welded joints, and no data available for low-cycle fatigue in plastic range.
