In this project phase, the behavior of elements resisting combined blast and fragment loading was studied further both in regard to reinforced concrete and sandwich structures. Firstly, a further study was conducted on reinforced concrete slabs. In this case, the residual capacity was calculated on the basis of fixed support conditions, as these would be more common in practical designs. The results of this study were then used to derive a single degree of freedom model which could describe the behavior of the slabs accounting for the projectile damage. Following this, the behavior of the sandwich and purely steel panels was studied further, repeating the quasi static tests performed on them in the past with a higher loading limit. Finally, additional impact tests were performed on sandwich panels to consider the effects of a different projectile shape.
