In order to apply the high strength bolted tensile type joint to civil steel structures' connections which are acted large sectional forces, Multiple bolts are needed. However, the tensile type joint with multiple bolt rows couldn't have the enough strength for the number of bolts. Therefore, this study conducted the tensile test to crarify the strength improvement of this joint by stiffening ribs. Consequently, we crarified that the use of stiffening ribs is effective in improving the strength of this joint up to the strength for the number of bolts.
