This study is an experimental study to investigate the performance of steel pipe flange joints, including theoretical yield and breaking strength formula, material test, and linear finite element analysis results. A total of 12 specimens with the various thickness of the flange plate and the number of joint bolts as variables (flange thickness: 3.2, 4.0, 4.5 mm, number of bolts: 4, 6) were prepared and a unidirectional tensile test was conducted. In order to investigate the performance of the joint, the plate thickness was designed to be thinner than the general case in order to induce flange fracture. When the flange thickness was the same, the yield strength and maximum strength increased as the number of bolts increased. However, when the flange thickness increased when the number of bolts was the same, the yield strength increased, but the joint stiffness increased and the maximum strength showed a tendency to decrease. Flange plate fracture was induced, but in the case of the specimen with 6 bolts, the steel pipe was fractured earlier than flage plate.
