- The numerical simulations presented in the present paper were on beam models geometrically identical to the beams previously tested in a shock tunnel but now provided with increased shear reinforcement consisting of vertical stirrups. The tested beam failed in brittle flexural shear during the blast loading in the tunnel. The results from the numerical investigation showed that brittle shear failures of beams subjected to blast loads may be prevented by dense shear reinforcement. The guideline for impulse loaded structure showed to underestimate the dynamic shear capacity as it is not dependent on the actual transverse reinforcement amount. This is however considered in the model used for determining the static shear capacity, meaning that further work developing a similar model fit to impulse loading is advised. To realize this development a new test series is proposed.
