Global System Considerations for Progressive Collapse with Extensions to Other Natural and Man-Made Hazards

“…A very important and innovative approach regarding disproportionate collapse global system considerations can be found in Ettouney, Smilowitz, Tang, and Hapij (2006). Important topics regarding the typology of disproportionate (or progressive) collapse have been published by Starossek (2009).…”

Publication details, including instructions for authors and subscription information: http://www.tandfonline.com/loi/nsie20The evaluation of the sensitivity or insensitivity of structures to local damage has been a major research field during the last decades, mainly provoked due to the series of aging structures and infrastructures. Many researchers have described this property as redundancy, others as the resistance to disproportionate collapse or robustness and still others as the ability of structural systems to display alternate load paths in case of a local damage. In any case, the problem for the evaluation of this property is increasingly alarming since many systems experience similar collapses (American Society of Civil Engineers (2009). Proceedings of Structures Congress on the first international symposium on disproportionate collapse. ASCE, Austin, TX). This paper presents the numerical assessment of disproportionate collapse analysis introducing the concept of partial damage of structural elements. Global robustness measures are proposed also for the case of multiple partial losses of adjacent elements. The measures are computed on the basis of a mathematical optimisation problem using collapse load analysis of steel frames with pre-existing damage. Results comparing the cases of partial losses with the full column losses are presented and discussed.

“…The ever-increasing concerns over the susceptibility of building structures to progressive collapse have spurred extensive research to accurately simulate such a chain reaction and understand the underlying mechanisms (e.g., [10][11][12][13]). Design optimization against progressive collapse provides a promising approach to achieving economy in building design while mitigating such rare yet devastating events.…”
