This paper presents the seismic behaviour of a ten-storey steel moment resisting frame. The structure, considered to be in a maximum seismic zone, has been designed with Eurocode 8. Two natural accelerograms and one artificially generated have been used as base excitations. The artificially generated accelerogram had maximum horizontal acceleration and spectral characteristics used for the design. For the analytical studies a computer model which describes numerically the cyclic beam-to-column joint and connection behaviour has been used. The study shows that flexible joints and connections provide a high ductility to the steel structure but directly affect the serviceability demand in the building due to increased inter-storey drifts.
