The research presented herein focused on improving the inelastic performance
of unreinforced welded steel moment connections. Both analytical and experimental
studies were conducted to investigate the effects of panel zone and to evaluate the
current panel zone design equations (AISC2000 and Michigan2001). The analytical studies included elastic and inelastic finite element analyses of exterior moment connections subjected to cyclic and monotonic loading. The experimental results used in this study were taken from inelastic cyclic tests of seven full-scale connection specimens carried out by other researchers. The results from analytical studies showed that stress distributions and force flows in the connection region are very complex and significantly different from what had been assumed in past design practice. The beam flanges have to carry a considerable shear force instead of the shear tab. This shear force can cause premature fracture of the beam flanges before they can participate in the inelastic response. As indicated by the experiment and the finite element analysis results, the panel zone design equation proposed by Arnon’s Model (Michigan2001) are shown to extraordinarily capture the whole shear response of panel zones better than Krawinkler’s Model (AISC2000). In addition, the new design procedure with the use of Michigan2001 design shear strength equation and the resistance factor of 0.9 was evidenced to successfully provide a balanced inelastic response between beam and the column panel zone. |
