The result of structural performance evaluation about circular CFT column-H shape steel beam which was performed as in previous study, even though we designed the Y type plate tension as below the axial force which was under design criteria, the flexure of steel beam was happened. For these reasons, in this study, to figure out the time of connections failure and the minimum value of parameters in order to evaluate the performance of advanced Y type plate in detail.
