To evaluate the ductility of high strength steel beam-to-column connections, Cycle loading connection test was conducted targeting HSA800 steel being developed in Korea and parameter is connection details. According to the study, The non-scallop detail and improved horizontal rib reinforcement detail used in this study enhanced deformation capacity of high strength steel connections which have brittle tendency by stress relaxation.
