“…The DIFs corresponding to the yield stress for steel obey the following expression according to [48]: (27) with f y the yield stress at strain rate˙ ; f y,st the static yield stress (here 500 MPa);˙ a strain rate between 10 −4 s −1 and 225 s −1 ;˙ st the 'static' strain rate of 10 −4 s −1 ; α = 0.074 − 0.040f y /414. As for concrete, the model is adjusted to match the results in [48] in terms of DIFs.…”

This contribution deals with the modelling of reinforced concrete (RC) structures in the context of progressive collapse simulations. One-dimensional nonlinear constitutive laws are used to model the material response of concrete and steel. These constitutive equations are introduced in a layered beam approach, in order to derive physically motivated relationships between generalised stresses and strains at the sectional level. This formulation is used in dynamic progressive collapse simulations to study the structural response of a multi-storey planar frame subjected to a sudden column loss (in the impulsive loading range). Thanks to the versatility of the proposed methodology, various analyses are conducted for varying structural design options and material parameters, as well as progressive collapse modelling options. In particular, the effect of the reinforcement ratio on the structural behaviour is investigated. Regarding the material modelling aspects, the influence of distinct behavioural parameters can be evaluated, such as the ultimate strain in steel and concrete or the potential material strain rate effects on the structural response. Finally, the influence of the column removal time in the sudden column loss approach can also be assessed. Significant differences are observed in terms of progressive failure pattterns for the considered parametric variations.

“…Stirrups exert lateral compressive stresses on concrete as it expands in the transversal directions due to loading, which improves the structural members strength and ductility. In several scenarios the ductility of the reinforced concrete members is of utmost importance, such as in progressive collapse (Menchel et al 2009;Hou and Song 2016;Petrone et al 2016;Rashidian et al 2016) and resistance against blast loading (Lim et al 2016;Codina et al 2016).…”

Apart from its recognized strengthening effect for shear loading, the presence of stirrups in reinforced concrete results in an increase of the ductility of structural members and in the capacity of reaching higher longitudinal compressive stress levels provided by transversal confinement. These effects are usually represented phenomenologically in fibre beam models by artificially increasing the compressive strength and the ultimate compressive strain of concrete. Two numerical formulations for layered beam descriptions accounting explicitly for transversal confinement are implemented and assessed in this contribution. The influence of stirrups is incorporated by means of a multi-dimensional yield surface for concrete, combined with equilibrium constraints for the transversal direction involving concrete and steel stirrups, and with a concrete ultimate strain dependent on the hydrostatic stress. This contribution focuses on the numerical formulations of both frameworks, and on their assessment against experimental results available in the literature. Keywords

“…Based on substantial research, a number of countermeasures for progressive collapse have been proposed [20,21], including the alternative path method [22], the enhanced local resistance method and the tying capacity design method. Furthermore, design codes and guidelines related to resisting progressive superstructure collapse have been issued in many countries [23][24][25][26].…”
