Abstract

Explosions bring a serious risk of damage or collapse when are produced inside buildings or in the close proximity. As the hazard intensity and possible effects are difficult to quantify, the structure should have the capacity to survive with inherent damages, thus preventing the progressive or disproportionate collapse. The measures for increasing progressive collapse resistance should be calibrated with reference to the type of structure analysed, and, in general, follow some common principles, e.g. hardening structural elements, providing additional load transfer routes or improving the continuity and tying. For existing buildings, strengthening may be necessary to provide or improve such abilities. In the paper, response against explosions of multi-story buildings is investigated and different intervention strategies are applied, considering both their efficiency and ease of application.
