ABSTRACT
Abstract This paper represents the results of some numerical simulations concerning the response of steel frames with semi-rigid joints under static and seismic loads. It was followed the influence of M-<(> model curve on the stability and seismic behaviour of steel structures. Also, it was studied the influence of semi-rigid joints on the seismic behaviour in comparison with the steel structures with rigid connections. It was tried to make a connection between the critical yield factor from the stability analysis and the q-factor from the seismic analysis. Keywords: Stability, Seismic Behaviour, Yielding, Hinge, Mechanism, Eigenperiod, q-factor.
