Analytical Tools for Progressive Collapse Analysis under Explosion

This paper will review the tools that are available for progressive collapse vulnerability analysis under explosion and compare them in term of capabilities and ease of use.Three usual methods which are used in designing explosion resistant structures are the indirect design approach, the alternate path design approach and the specific local resistance direct design approach.The differences between progressive collapse analysis and routine structural analysis, the needed capabilities in computational tools, comparing available tools and verification of predictive capabilities will be investigated in this paper.
