Blast incidents in recent years show that most of the terrorist attacks on public structures were explosions within short stand-off distances. In this context, columns are the most vulnerable structural components and their failure is the primary cause for progressive collapse in framed structures. On the other hand, many of ...

The material constitutive relationship is not only the conclusion of some regulations summarized from experimental data, but also plays an important role in numerical simulations. It reflects the realistic physical and mechanical properties of materials as much as possible to improve the accuracy of numerical results. At present, various kinds ...

As a result of the ever increasing threat of terrorist activity, countless effort has been made to mitigate blast effect on structures so that they can withstand more severe explosion accidents without catastrophic failure, thus to reduce the number of human casualties. Indirect means such as using blast barrier to ...
