Abstract
This study proposes a blast load model that generates multiple impulse curves with appropriate shapes depending on the scaled distance and, thus, precisely calculates the blast load distribution over the structure surface. The suitability of the proposed model is examined by using the finite element simulation of a blast test with steel plates and comparing the predicted deflections with the measurements. The results reveal that the proposed model accurately calculates the blast load distribution over the structure surface. The predicted deflection profiles of the steel plates are closer to the measured deflection profiles when the proposed model is employed, as compared to the existing models, which produce only a single impulse curve.
