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.

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.

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.

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

Limiting the possibility of progressive collapse

Building Research and Practice, 1974
The 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 simulation in RC Structures

2008
Throughout recent history, famous records of building failures may be found, unfortunately accompanied by great human loss and major economic consequences. One of the mechanisms of failure is referred to as ‘progressive collapse’: one or several structural members suddenly fail, whatever the cause (accident or attack).

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.

Collapse of the United Progressive Alliance

2022
Abstract The Congress-led United Progressive Alliance (UPA) government that came to power in 2004 functioned well under UPA-1 (2004–9) but faced numerous challenges under UPA-2 (2009–14). This chapter seeks to understand how and why a government, which had been sufficiently popular during its first term to be re-elected in 2009 with a ...
