This paper reports on a study on the dynamic behaviour of steel moment resisting frames with a concrete slab on metal sheeting. The experimental analysis, which is herein summarized, consists of two different series of tests: 1) component tests on beam-to-column joints under quasi-static cyclic reversal loading and 2) dynamic tests of complete full scale framed structures on the shaking table. Performance of joints and main parameters affecting their response are identified and discussed. Experimental results are also considered with reference to low-cycle fatigue behaviour and the associated fatigue resistance line are presented. Moreover, the performance of the joints in the frame under dynamic loading is analyzed and a simplified approach, which can be used for design purposes, is applied to monitor the damage accumulation process in steel framed structures under seismic action.
