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 ...

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 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.

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.

Disproportionate Collapse Design Considerations — A Comprehensive Approach

Structures Congress 2014, 2014
Recent efforts to develop progressive collapse guidelines in the United States reveal an interest in improving design requirements to address disproportionate collapse, especially in the context of blast-resistant design. As a result, several ongoing research projects are investigating structural response under disproportionate collapse conditions ...

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

Disproportionate collapse resistance of buildings during retrofitting

2021
In recent years, research on progressive collapse and robustness of structures has significantly increased. According to national and international building codes, the structure should be able to avoid partial or total collapse under extreme events, such as fire, explosions, impact or consequences of human error.

Disproportionate collapse: a pragmatic approach

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2007
Probability-based design methods face certain problems in making structures sufficiently collapse resistant and thus preventing disproportionate collapse. These problems are addressed and a discussion is given to outline how they might be overcome both within and outside a probabilistic framework.

Approaches for Design to Resist Disproportionate Collapse

Structures Congress 2009, 2009
SEI’s Progressive Collapse Standards and Guidance Committee is developing a guidance document to address collapse resistance in buildings. This comprehensive guidance document will support existing design standards and building codes and may be applicable to buildings and structures only as dictated by local statute.
