Abstract
The current research activity deals with the seismic design of perimeter steel moment resisting
frames of 9, 7and 5 storeys with several span lengths(9.15m, 7.63m, 6.54m and 5.08m) using
Eurocode 8. In total 24 cases are designed and analysed using Ductility Class High(DCH) having
behaviour factor equals 6.5. In order to shed light on the drift limitations of Eurocode 8, the designed
frames are then checked by means of iteration to investigate the optimal behaviour factor. The
evaluated behaviour factor is then compared with the code provided behaviour factor and with the
evaluated ductility factor of frames, obtained through the use of static nonlinear analysis. Hence the
influence of drift criteria on the capacity design rules of Eurocode 8 is investigated. The frame
performances are measured in terms of over strength and redundancy factors, strength demand to
capacity and drift demand to capacity ratios allowing to the point highlighted conclusions.
