heal.abstract	Innovative dissipative (INERD) connections were developed for seismic resistant braced frames. The dissipative zones in such frames are the connections, while the braces are protected against buckling. This paper presents studies on the INERD pin connections, where the braces are connected to their adjacent members by means of eye-bars and a pin running through them. Experimental and theoretical investigations show a high energy dissipation capacity that is due to the inelastic bending action of the pin. The susceptibility to brittle fracture or low-cycle fatigue is low as inelastic action takes place away from welds or stress concentrations. Design rules for the connections are developed. The behaviour of braced frames with dissipative connections under seismic loading is examined in comparison to conventional concentric braced frames. The beneficial mechanical behaviour and other constructional advantages provide a promise for a wide application of the invented connections for engineering structures in seismic regions. © 2006 Taylor & Francis Group.	en
