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.

Formulations for probability of progressive collapse

Structural Safety, 1988
Abstract Practical and tractable formulations for determining the probability of progressive collapse in structures are developed. Both the case where abnormal loads are specified and the case where initiating damage levels are specified are considered. Methods for including event control measures in the formulations are also obtained.

Progressive quantum collapse

American Journal of Physics, 2022
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, 2005
A 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.

Progressive collapse in an eccentric braced frame through extended progressive collapse analysis algorithm

Asian Journal of Civil Engineering, 2021
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, 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 ...
