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 ...

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.

Progressive Collapse Resistance of Emulative Precast Concrete Frames with Various Reinforcing Details

Journal of Structural Engineering, 2021
In this paper, three precast concrete (PC) frames and one cast-in-situ reinforced-concrete (RC) frame were cast and tested to investigate the load-resisting mechanisms of emulative PC frame...

Progressive Collapse Analysis of the Champlain Towers South in Surfside, Florida

Journal of Structural Engineering
18 Since the Ronan Point collapse in the UK in 1968, the progressive collapse analysis of 19 residential buildings has gradually drawn the attention of civil engineers and the scientific 20 community.

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 COLLAPSE RESISTANCE OF FACILITIES EXPERIENCED TO LOCALIZED STRUCTURAL DAMAGE - AN ANALYTICAL REVIEW

Building and reconstruction, 2021
During the entire life cycle, the facilities are experienced to force and environmental actions of various nature and intensity. In some cases, such influences can lead to a loss of the bearing capacity of the structural elements of a building, which in ...

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.
