A series of numerical simulations were performed on reinforced concrete cladding panels with different curvatures subjected to explosive loading. The LS-DYNA finite element program along with the Concrete Damage Model was used to develop the numerical model and calibrated using the results of existing explosive trials. Both convex and concave shaped single curvature panels were assessed along with standards flat panels for the blast performance. Two different connection types were considered for the evaluation, which were identical to those used in the original explosive trials, named as dowelled type and angle cleat type connections. Improved performance with reduced transverse deformations was observed for the convex shaped panels in comparison with the original flat panel. However, concave shaped panels exhibited a more flexible response. Connection forces did not exhibit a significant variation although the panel response was different with change in curvature.
