Previously, the authors carried out the static and the fatigue tests on various welded joints of the mild steel and the high tensile strength steel tentatively manufactured by the JSTM, and made a proposal on the allowable stress in the designs of welded steel bridges. In this experimental research, (1) the authors carrid out the fatigue tests on butt welded joints connecting the thick plates of high tensile strength structural steel, under the repeated stresses of completely reversed type -σ_<max>〜+σ_<max>, partly reversed type -6kg/mm^2〜+σ_<max>. and pulsating type 0〜+σ_<max>., +6kg/mm^2〜+σ_<max>., +12kg/mm^2〜+σ_<max>., +20kg/mm^2〜+σ_<max>.. The results of the present tests were compared with those of previous tests. (2) Moreover, the authors studied the effect of the treatment of the welded part on the fatigue strengths.
