Experimental Study of Ductility of Steel Frames With Saddle-Like (Khorjeeni) Connections

In this research, two types of steel frames with saddle-like connection were tested. They were: a) unbraced frames with modified Khorjeeni connection and, b) braced frames with conventional Khorjeeni connection. Four half scale models of the above mentioned frames were tested in laboratory under semi-dynamic cycles of loading. From these experiments the ductility factor, p., for unbraced frames were found to be at least equal to 2.4 and for braced frames to be equal to 2.0.
