Synopsis : Numerical modelling is nowadays commonly employed in the analysis of concrete structures subjected to extreme dynamic loadings such as blast. Sophisticated material models, particularly concrete, are available in commercial codes and they are often applied in their default settings in a diverse range of modelling applications. However, the mechanisms governing different load response scenarios can be characteristically different and as such the actual demands on specific aspects of a material model differ. It is therefore not surprising that a well-calibrated material model may exhibit satisfactory performance in many applications but behave unfavourably in certain other cases. Modelling the response of reinforced concrete structures to blast load presents such an important scenario in which the demands on the concrete material model are considerably different from high-pressure scenarios for example high-velocity impact or penetration. This paper stems from an initial modelling undertaking in association with the Blind Blast Contest organised by the ACI Committee 370, and extends to a detailed scrutiny of the demands on the concrete material model in terms of preserving a realistic representation of the tension/shear behaviour and the implications in a reinforced concrete response environment. Targeted modifications are proposed which demonstrate satisfactory results in terms of rectifying the identified shortcomings and ensuring more robust simulation of reinforced concrete response to blast loading.

The work done in this research is to study the response of reinforced concrete slabs subjected to blast loading as they can be used as protective structures around the main structure. An experimental investigation has been performed in a separate study involving blast-testing of 12 reinforced concrete slabs in a shock tube (Blast Load Simulator). The data from this experimental investigation was made available for performing advanced finite element analysis done in this research to study the behavior of these slabs towards blast loading. A non-linear transient dynamic finite element analysis program LS-DYNA® is used for this study. The finite element models of these 12 slab panels are developed in LS-DYNA® and blast pressures equivalent to those generated in the experiment are applied to them. These slabs include two material combinations based on their strength namely, the high-strength concrete reinforced with high-strength steel slabs and normal-strength concrete reinforced with normalstrength steel slabs. The primary objective is to study the response of material combinations to blast loading by using two different concrete material models available in LS-DYNA namely, Winfrith Concrete Model and Concrete Damage Model Release 3 and comparing it with the experimental results. Validation of these models with experimental data will provide a
