Moment–shear interaction of stiffened plate girders — Numerical study and reliability analysis
Abstract The paper deals with the resistance of longitudinally stiffened plate girders subjected to moment–shear interaction. Based on a verified numerical model an extensive numerical parametric study was performed. Altogether 630 girders were analysed and the results were used for reliability analysis of resistance models. Five different resistance models were considered and the corresponding partial safety factors were determined. The resistance models were: moment–shear (M–V) interaction model from EN 1993-1-5, modified M–V interaction model, gross cross-section bending resistance model and two additional resistance models that present combination of the first three resistance models. It was shown that M–V interaction can be covered using EN 1993-1-5 M–V interaction resistance model with partial safety factor 1.1 or with only bending resistance check of gross cross-section taking partial safety factor equal to 1.1.
Highlights Numerical parametric study Behaviour of longitudinally stiffened girders under bending–shear interaction Development of new resistance models. Comparison of numerical results with new and EN 1993-1-5 resistance models Statistical evaluation and determination of partial safety factors
