Typology of progressive collapse
Engineering Structures, 2007Abstract 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.

Instantaneous collapse of the wave function upon measurement of a single particle is one of the postulates of the Copenhagen interpretation of quantum mechanics. However, what happens when a many-body system in a macroscopic coherent state is measured one particle at a time? Here, we consider successive measurements of individual spins from a spin Bose

Collapsing Words: A Progress Report
International Journal of Foundations of Computer Science, 2005A word w over a finite alphabet Σ is n-collapsing if for an arbitrary DFA [Formula: see text], the inequality |δ(Q, w)| ≤ |Q| - n holds provided that |δ(Q, u)| ≤ |Q| - n for some word u ∈ Σ+(depending on [Formula: see text]). We overview some recent results related to this notion.

This study examines the progressive collapse in an eccentric braced frame (EBF) with shear link designed through extended progressive collapse analysis algorithm (EPCA) using Iranian codes of practice for seismic resistance. The algorithm can determine the prominent parameters in progressive collapse analysis such as failure modes, failure loads ...

Human Progress — And Collapse?
Energy & Environment, 2005Against 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 ...

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.

Limiting the possibility of progressive collapse
Building Research and Practice, 1974The chance of progressive collapse is not confined to panel-frame buildings, though the latter may be more exposed to the danger. The following statement is issued by CIB Working Commission W23A on loadbearing walls and accordingly deals with the subject in the context of loadbearing walls.

Progressive collapse resistant design
Computer-Aided Design, 1983Progressive 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.
