Progressive collapse resistant design

Computer-Aided Design, 1983
Progressive collapse is a situation in which a localized failure in a structure, caused by an abnormal load, triggers a cascade of failure affecting a major portion of the structure. Several buildings have collapsed in this fashion in recent years, and the possibility of progressive collapse is a source of continuing concern.

Bridge Progressive Collapse Vulnerability

Journal of Structural Engineering, 1997
For important structures, it is increasingly required that catastrophic failure of the entire structure be prevented. Failure of an element due to an accidental event must not result in progressive collapse of other elements or of the whole structure. Studies to comply with this requirement for a bridge of numerous spans are presented. Dynamic analyses

Progressive Analysis Procedure for Progressive Collapse

Journal of Performance of Constructed Facilities, 2004
Following the collapse of the World Trade Center towers in September 2001, there has been heightened interest among building owners and government entities in evaluating the progressive collapse potential of existing buildings and in designing new buildings to resist this type of collapse.

Human Progress — And Collapse?

Energy & Environment, 2005
Against the human experience of long-term stagnation and misery, the record of growing prosperity over the past two centuries, and in particular the last fifty years, is astounding. Economic growth owes much to the mobilisation of resources and structural flexibility, but this depends on the ‘software of economic development’ – institutions, which ...

Progress in Collapse Analyses

Journal of Pressure Vessel Technology, 1987
In the field of finite element structural analysis, the computation of collapse states of structures prone to unstable behavior has long been considered a difficult if not intractable problem. Only recently have procedures that deal effectively with this difficulty found their way in general-purpose finite element codes.

Approximations in Progressive Collapse Modeling

Journal of Structural Engineering, 2011
Assumptions must necessarily be made when the collapse response of structures is investigated using simulation models. The type and extent of modeling assumptions depend on the computational resources available, modeling expertise, and results sought.

Typology of progressive collapse

Engineering Structures, 2007
Abstract A typology and classification of progressive collapse of structures is developed that is founded on a study of the various underlying mechanisms of collapse. Six different types and four classes are discerned, the characteristic features of each category are described and compared, and a terminology is suggested.

Reliability‐Based Progressive Fatigue Collapse

Journal of Structural Engineering, 1983
General relationships between individual joint reliability and overall system reliability in a redundant structure with no repair program are presented. Using a fatigue reliability model, a Monte Carlo analysis provided a distribution of time to failure for various degrees of redundancy.

Classification and Nomenclature: Progressive Collapsing Foot Deformity

Foot & Ankle International, 2020
Recommendation: The historical nomenclature for the adult acquired flatfoot deformity (AAFD) is confusing, at times called posterior tibial tendon dysfunction (PTTD), the adult flexible flatfoot deformity, posterior tibial tendon rupture, peritalar instability and peritalar subluxation (PTS), and progressive talipes equinovalgus.
