EFFECT OF TENSILE FORCE AND SHEAR FORCE ON BENDING STRENGTH AND STIFFNESS OF HIGH STRENGTH BOLTED TENSILE JOINTS

Abstract

High Strength bolted tensile joints are classified into both tension type joints and friction type joints because of the existence of compression force between two tee flange plates due to high bolt pre-stress force. That is, high strength bolted tensile joints subjected to shear force also work as the friction type joint. Most of the past studies concerning this type joint have been mainly investigated on the mechanical behavior subjected to only tensile force. Therefore, in order to apply this type of joints to actual connections of steel bridge members, the behavior under various combinations of axial force, bending moment and shearing force must be investigated. In this study, an experiment has been carried out for the specimens modeled as connections of box members subjected to tensile force, bending moment and shear force. And the effect of tensile force and shear force has been discussed.
