ABSTRACT
In this paper, test results on the strain rate effects on the cyclic behaviour of steel beam-to-column joints in moment-resisting frames are presented. Twelve full scale specimens have been tested under constant amplitude cyclic loading, for three connection typologies, for three different steel grades and for two different loading speeds. Qualitative conclusions are drawn in term of strength, energy dissipation and degradation. Test results are finally compared in term of low-cycle fatigue endurance.
