Civil structures subjected to strong earthquakes need to dissipate large amounts of energy. Hence, the conventional systems suffer significant inelastic deformations (costly damages) in main structural elements (steel beams, columns and concrete slabs) and residual interstorey drifts after a strong seismic event. Repair work, however, in these cases is most of the time not feasible, or too expensive. FUSEIS Bolted Beam splices, therefore, can be installed in buildings in order to protect the structural elements during the seismic events. On the other hand, behaviour factor in EC8 is provided only for conventional frames such as MRFs, CBFs, EBFs and so on without any clear specification for other types of structures i.e. innovative dissipative structures. This paper investigates the seismic performance of buildings having FUSEIS bolted beam splices by means of non‐linear static analysis, results also compared with conventional frames. Behaviour factor of these buildings are then evaluated based on single degree of freedom systems. This paper investigates one of the several possibility of the calculation of the behaviour factor based on SDFS. The other possible methods will be deeply study in the upcoming paper. In order to do so, three buildings regular in and elevation has been deeply investigated as case studies. Numerical results highlight that plastic deformation concentrates mainly in the beam splices, hence, remaining the main elements in elastic region and hence protecting them from any sort of damages.
