Abstract
The paper deals with the numerical analysis of concentrically braced steel frames under severe seismic loading. The characteristics of the finite element adopted for modelling axially loaded bars are briefly summarized while the procedure for dynamic nonlinear analysis is described in some detail. Examples of application are then given for different types of one-storey bracing systems. The design criteria are described as well as the dynamic modelling assumptions. The results of dynamic step-by-step analysis, performed on the basis of artificial spectrum-compatible accelerograms, are then given in terms of peak local ductility demands and estimates of optimal behaviour factors; a modification is also proposed for the Eurocode 8 design response spectrum.
