Avoiding Disproportionate Collapse in High-Rise Buildings
Structures Congress 2008, 2008Accidental circumstances must not result in progressive and disproportionate collapse. Strategies for achieving this goal are studied and corresponding design concepts are developed. The focus is on large and slender high-rise buildings with a high degree of significance and exposure.

Design for Disproportionate Collapse Prevention of Precast and Prestressed Structures
Structures Congress 2013, 2013Due to the use of discrete connections, traditional precast and prestressed concrete structures are often susceptible to disproportionate collapse. This perceived weakness discourages the use of precast systems for high-risk facilities such as those used by the United States Federal, State, and Military groups.

Assessment of disproportionate collapse behavior of cable stayed bridges
Bridge Structures, 2016Although the application of the Alternate Path method has well proven its efficiency towards increasing the structural robustness of bare frame structures against progressive collapse, it should be further developed for bridge structures, and especially cable stayed bridges, as they are the only type routinely designed for cable loss phenomenon.

Disproportionate Collapse in Building Structures.
2011The failure of the Ronan Point apartment tower focused interest in disproportionate collapse, and prompted the ?Fifth Amendment? to the UK Building Regulations which was introduced in 1970. From this point on structures were required to exhibit a minimum level of robustness to resist progressive collapse.

Abnormal Loads and Disproportionate Collapse: Risk Mitigation Strategies
Structures Congress 2009, 2009A disproportionate (or progressive) collapse of a building or other structure is one that initiates from local damage and subsequently propagates to encompass a major portion of the facility. Current concerns with such collapses stem from changes in building practices and sociopolitical challenges that have highlighted the importance of hazards that ...

Risk Assessment to Support Design to Resist Disproportionate Collapse
Structures Congress 2009, 2009The ASCE SEI Committee on Progressive Collapse Standards and Guidance is developing a guidance document to address collapse resistance in buildings. The document will provide a variety of approaches for design to resist disproportionate collapse. In addition to providing design approaches, the document will also include guidance for owners, architects,

Design of a High-Rise Steel Building to Resist Disproportionate Collapse
IABSE Reports, 2014<p> This paper will present information on practical design methods and verification procedures which can be used for design against disproportionate collapse, as relevant to high-rise buildings. The case study of a 30 story high-rise commercial office building will be given.

Steel Moment Frame Connection Performance Limits for Disproportionate Collapse
20th Analysis and Computation Specialty Conference, 2012Disproportionate collapse is an extreme loading event requiring consideration of all available load paths within a structure. Current criteria quantify acceptable performance limits through the use of seismic documentation. For steel moment frame structures, specifically, ASCE Standard 41-06 is used to quantify a loss of moment resisting capacity in ...
