みぞ形鋼と鋼板をすみ肉溶接した接合部の疲労強度

抄録

Steel and concrete composite deck, which is arranged channel shape steel members in the transverse direction on the top surface of the bottom steel plate, has been investigated by the authors. By the arrangement of channel shape steel members welded to the bottom steel plate, the steel and concrete composite deck with cellars in the concrete becomes to be more lightweight than typical types of steel and concrete composite decks. For highway bridge decks, it is very important to verify the fatigue strength of the welded joint. In this paper, fatigue tests of the welded joint between the channel shape steel and the bottom steel plate were carried out under the tensile fatigue stress.
