A. Osman et al., IMPLICATIONS OF DESIGN PHILOSOPHIES FOR SEISMIC RESPONSE OF STEEL MOMENT FRAMES, Earthquake engineering & structural dynamics, 24(1), 1995, pp. 127-143
During a severe earthquake, steel moment resisting frames are expected
to experience significant inelastic deformation in their members and
joints. This behaviour is dependent upon several design parameters suc
h as member sizes, frame's overstrength, member deformation capacities
and the detailing of components. In this study, the influence of such
aspects on the inelastic response of frames is investigated. Inelasti
c static and dynamic analyses were performed on four frames of differe
nt designs for a typical six-storey building The frames were designed
and detailed in accordance with current North American code requiremen
ts. The computed response of each frame was compared with the behaviou
r expected by the codes. Recommendations for a design procedure are su
ggested for improving the structural performance of low-rise steel fra
mes subjected to strong earthquake excitation.
