Use of high-strength steel and adoption of hybrid c01mections of welded joints and bolted joints are factors for rationalizing designs of steel bridges. In this study, tensile tests and elasto-plastic analyses were perfonned on these joints made of three types of steel with different tensile strengths and under-matched weld metals.Furthermore, the slip coefficients of bolted joints, which slid on the condition of bolts being tightened up to 60% of design level and then the bolts were tightened up to the deign level, are discussed through a series of experiments in which the direction and the amount of pre-sliding are set as the parameters.
