Abstract— An experimental study was carried out to investigate the low-cycle fatigue behaviour of steel beam and beam-column members, as well as of steel connections, with particular emphasis on beam-to-column joints. Several full-scale specimens were tested, in a multi-specimen testing program, using constant-amplitude displacement histories, to develop a cumulative-damage model. Variable amplitude tests were carried out in order to verify the validity of the proposed model.It is shown that the S-N curves given by codes for high-cycle fatigue can be used to interpret the low-cycle fatigue behaviour of steel members and connections. Miner's rule can be used, together with the previously defined S-N curves and with a cycle counting method to define a unified cumulative damage model valid for both high and low cycle fatigue. A general failure criterion is proposed which considers the actual energy dissipation through plastic deformation.
