Survey of contemporary practices for disproportionate collapse prevention

Engineering Structures, 2019
Abstract This paper summarises contemporary practices and implementations of the existing codes and guidelines with respect to disproportionate collapse prevention. Here, focus is given to structural robustness, defined as the ideal method to decrease the probability of disproportionate collapse in buildings following an initial damage.

Avoiding Disproportionate Collapse of Major Bridges

Structural Engineering International, 2009
Avoiding disproportionate collapse following some small triggering event is an important aspect in the design of major bridges. A general approach for designing structures against disproportionate collapse is outlined and applied to bridges. Compared with buildings, bridges are primarily horizontally aligned structures with one main axis of extension ...

Avoiding Disproportionate Collapse of Tall Buildings

Structural Engineering International, 2008
Accidental circumstances must not result in disproportionate collapse. Strategies for achieving this goal are studied and corresponding design concepts are developed.

Assessment of disproportionate collapse behavior of cable stayed bridges

Bridge Structures, 2016
Although 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.

Avoiding Disproportionate Collapse in High-Rise Buildings

Structures Congress 2008, 2008
Accidental 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.

Steel Moment Frame Connection Performance Limits for Disproportionate Collapse

20th Analysis and Computation Specialty Conference, 2012
Disproportionate 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 ...

Risk Assessment to Support Design to Resist Disproportionate Collapse

Structures Congress 2009, 2009
The 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,

Abnormal Loads and Disproportionate Collapse: Risk Mitigation Strategies

Structures Congress 2009, 2009
A 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 ...

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 ...

SEI Pre-Standard and Commentary on Disproportionate Collapse (Part II)

IABSE Congress, Chicago 2008: Creating and Renewing Urban Structures – Tall Buildings, Bridges and Infrastructure, 2008
<p>At lower levels of risk, prescribed levels of appropriate robustness could be incorporated into the structural elements and system, even in the absence of specified threat or probability of occurrence. As a minimum, robustness can be added to an element or system through the prescription of integrity requirements such as element to element ...
