The flexible-stiff mixed structure, where the main frame is used as a flexible element and the earthquake input energy is mainly absorbed by energy absorption element, is suggested to enable an effective earthquake resistant design. In order to achieve such flexible-stiff mixed structure, a connection with a slit-type steel plate damper installed at each ends of wide-flange section beam, as an energy absorption element, was proposed through this research. A series of experiment was carried out to evaluate their structural performance and behavior. The main parameter of 'experiment was the aspect ratio of the struts in slit plates. Experimental results indicates that most of the energy was absorbed by plastic deformation of slit plate dampers. Additionally, the behavior of such type of connection can be expressed into the sum of the behavior of non-diaphragm connection, where only the web of beam is welded to the column, with that of the slit plate damper.
