Cyclic loading tests were carried out to investigate the effects of end-tab on plastic rotation capacity of H-beam connected with SHS-column. In the specimens used steel end-tab plate, the specimens with leaving end-tab and cutting off a circular arc part were fractured by premature cracks at bottom of slit between beam flange and steel end-tab plate. The specimen with the steel end-tab leaving 5mm width also fractured at bottom of the slit. However the plastic rotation capacity was improved. To use L-shaped end-tab made by ceramic was the most effective method for improving the plastic rotation capacity.
