Abstract—This paper focuses on steel columns with flange joints in prefabricated steel frame structures. To investigate the compressive performance of such steel columns, fifteen specimens were tested. The experimental results indicate that, compared to non-joint columns, the bearing capacity and bending stiffness of high-strength bolt joint columns and bolt tapping columns are less, but they can transfer the compressive load better. The failure mode of the steel columns was ductile failure. This study aims to promote the adoption of prefabricated steel frame structures and the improvement of standards.
Index Terms—Compressive behavior, prefabricated steel frame structure, high-strength bolt joint, bolt tapping joint.
