Ductile Moment Resisting Connections by Means of Drilled Cover Plates

H. Farrokhi, F. Danesh and S. Eshghi

Abstract:
Seismic behavior of a typical steel moment resisting connection is investigated and the influence of the connection behavior on the global frame performance is studied. It is proposed to shift the stress concentration from the connection face trough the cover plates by means of drilled holes. This will eliminate the unfavorable cracking mode and enhances the overall connection behavior. Based on finite element results, while the weld roots are released from stress concentrations, the sensibility of the weld root quality is diminished and the global structural performance and reliability is significantly improved.
