Second-order inelastic analyses in ultimate limit state design of frame structures
Abstract
This paper presents a robust procedure to calibrate nonlinear formulations so as to predict first member failure in accordance with recognized design equations. The procedure accounts for residual stresses and geometrical imperfections through an equivalent out-of-straightness for each member. It is shown that, for most of the cases studied, there is excellent agreement between first member failure predictions of the (calibrated) second-order inelastic analysis and conventional design equations using budding lengths determined through refined analyses.
