Conventionally,the blast-resistant structures,such as blast door panel,are designed and fabricated with solid materials of huge weight to resist disastrous blast or high velocity impact loads. This not only increases the material and construction costs,but also undermines the operational performance of the protective structures. To overcome these problems,many researchers try to use high-strength materials and different structural forms in structural design to resist the high blast and impact loads. This study introduces a new configuration of door panel with a structural form of multi-archedsurface. Its energy absorption and blast loading resistance capacities are numerically investigated by using finite element code Ls-Dyna. To calibrate the numerical model,some existing panels are also modeled. The results are compared with the existing numerical and testing data. The calibrated model is used to simulate the responses of curved panels with different number of arches. In comparison with the results,it is found that the proposed new multiarched door panel performs better than other forms of panels in resisting the blast loadings. This new arched door panel can be employed to mitigate blast loading effects in structural panel design.
