Abstract: Three monotonic and nine cyclic tests have been performed at the National Institute of Applied Sciences (INSA) of Rennes-France on bolted beam-to-column steel and composite moment resisting joints. For composite joints the slab is composite with a profiled steel sheeting connected by means of welded headed studs to the steel beam. Both external and internal joints of frames are considered with two types of loading: symmetrical and unsymmetrical. The dissipation of plastic energy is made either inside the joint using thin end-plates, or outside the joint in the connected beam using bolted end-plates strengthened by adjacent haunches. The cyclic testing procedure recommended by the European Convention for Constructional Steelwork (ECCS) has been applied in order to simulate sever seismic actions. The experimental results are discussed in terms of rotational stiffness, moment resistance, rotational ductility and low-cycle fatigue with comparisons to analytical models given in Eurocodes 3 and 4.
