Evaluating Disproportionate Collapse Vulnerability

International Journal of Protective Structures, 2015
Adding resilience and robustness to the infrastructure vis-à-vis reducing risks related to disproportionate collapse of the structural framing system of a facility, has become a concern in the engineering design communities in several countries, but particularly in the U.S. The idea is to address a perceived weakness in design standards related to the

Disproportionate Collapse: Terminology and Procedures

Journal of Performance of Constructed Facilities, 2010
A variety of terms are used to describe structural characteristics and concepts in the context of disproportionate collapse of structures. Some of these terms, namely collapse resistance, robustness, and vulnerability as well as redundancy, continuity, ductility, and integrity are discussed in this paper.

Preventing Disproportionate Collapse

Journal of Performance of Constructed Facilities, 2006
“Disproportionate collapse” is structural collapse disproportionate to the cause; it is often, though not always, progressive, where “progressive collapse” is the collapse of all or a large part of a structure precipitated by damage or failure of a relatively small part of it. There have been many attempts to develop design guidelines and criteria that

Practical Means for Energy-Based Analyses of Disproportionate Collapse Potential

Journal of Performance of Constructed Facilities, 2006
For several decades, the engineering profession has considered techniques to analyze the potential that structures could experience disproportionate collapse and to design them for greater resistance to such collapse. First interest in such design followed the partial collapse in 1968 of the Ronan Point building in London, a high rise residential ...

Disproportionate Collapse Simulations

Applied Mechanics and Materials, 2016
In recent years the ability to simulate and predict disproportionate collapse has seen growing interest among the scientific community. This is a challenging matter, since many authors have been dealing with the modeling of progressive collapse, and it is now well-established that such problem requires the use of many different non-standard modeling ...

Disproportionate Collapse Research Needs

Structures Congress 2009, 2009
Mechanisms of progressive collapse resistance are described which help identify new design requirements that effectively improve collapse resistance of structures. Criteria must be established to identify structures for which progressive collapse resistance may need to be enhanced through the implementation of additional design requirements.
