The precise study of connections performance in a steel structure is important. End plate connections are commonly used in steel structures. In this research, the cyclic behavior of cantilever beam connection to the endplate column under cyclic loading has been evaluated. In the calculations, all of the parameters affecting the behavior of this connection have been investigated and solutions are proposed to reach the maximum connection capacity. Two general models of connecting beams to different columns have been considered for the research with beams of 30 and 40 centimeters depth. The end plate thickness, end plate shape, column thickness, strength or the material of the bolt, necessity of using the continuity plate, double and gusset plate, are the parameters that were considered in the analyzes. According to the results of this study, the use of a thin end-plate causes localized buckling in the plate. The use of continuity plates is very important and prevents local buckling in the panel zone. It is also necessary to use a double plate if the column web is thin. Also, the use of gussets improves the flexural strength of the section.
