ABSTRACT
Paragraph 2 of the paper is devoted to basic design methods for a beam-to-column joint simply fastened to the column flanges by bolted plates welded to the beam ends. After briefly pointing out important detailing aspects related to the bolts and welds, different force distributions in the bolt-rows are considered to over-strength the joint suitably in terms of the structural ductility class. Paragraph 3 takes the previous approach again (only for classes DCH and DCM) when the use of haunch is deemed as an appropriate solution of over-strength. Finally, paragraph 4 illustrates the above theoretical approaches by showing the corresponding solutions of joints for a typical moment resisting frame in seismic zone.
