The Steel/RC composite Column-beam connection joint is
considered one of the most important subjects in framed
construction. Ductility has the most influence among other
factors that control the behavior of this joint, and the nonlinear
behavior
of this joints when subjected to large and cyclic
loading is dominated by several parameters. These parameters
reflect the assembled components of the joint for every
component has a distinguished material and therefore specific
behavior under the loading corresponding to it.
