Abstract
Frames consisting of composite reinforced concrete and steel (RCS) have been considered as structural systems for several years. This system benefits from the advantages of both systems by optimally combining steel and concrete structural elements. These connections are of two types, which include connections with a through-beam and connections with a through column. In this research, the laboratory model of previous studies has been simulated in ABAQUS finite element software and the seismic performance of RCS joints under cyclic loads and uniform loads was investigated. After validating the finite element model, a parametric study (checking the thickness of the steel panel in the joint area, checking the thickness of the cover sheet, etc.) was performed. Finally, after comparing the results of this type of connection, a modified model was presented which, in addition to increasing the capacity, shows a much more stable and desirable behavior.
