AbstractKhorjini (satchel) connection is one of the beam-to-column connections in steel frame structures. It has become especially popular in Iran for conventional buildings, due to its speed and convenient in construction process and economic privileges in comparison to the other types of steel connections. Connecting two uncut beams to both side of a column by means of top and seat angles is a method for building a common type of Khorjini connection. In this study, experimental results of loading tests on six different types of mid-span Khorjini connections subjected to static cyclic unidirectional reverse lateral load and applied axial load were presented. The six specimens were design with different details of strengthening on the connection components in order to improve the bending moment capacities, stiffness and rigidity percentages and shear capacities of the satchel connections. Simplicity on installation and building of the connections are the other important parameters that have been taken into account in the design. In addition post-earthquake damage inspection results after Dec. 26, 2003 Bam-Iran earthquake on steel frame buildings with satchel connections are presented. The results of the inspection and the experimental study on Khorjini connections were discussed and some efficient improvements on Khorjini connections were suggested.
