Progressive Analysis Procedure for Progressive Collapse
TLDR
In this article, the authors present four more sophisticated analysis procedures for evaluating the progressive collapse hazard of existing buildings: linear-elastic static, nonlinear static, linear linear dynamic, and nonlinear dynamic.Abstract:
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. The General Services Administration and Department of Defense have issued general guidelines for evaluating a building’s progressive collapse potential. However, little detailed information is available to enable engineers to confidently perform a systematic progressive collapse analysis satisfying these guidelines. In this paper, we present four successively more sophisticated analysis procedures for evaluating the progressive collapse hazard: linear-elastic static; nonlinear static; linear-elastic dynamic; and nonlinear dynamic. We discuss the advantages and disadvantages of each method. We conclude that the most effective analysis procedure for progressive collapse evaluation incorporates the advantageous parts of al...read more

ReportDOI
Development of progressive collapse analysis procedure and condition assessment for structures
TL;DR: Progressive collapse as discussed by the authors is defined as the loss of load-carrying capacity of a relatively small portion of a structure due to an abnormal load which, in turn, triggers a cascade of failures affecting a major portion of the structure.
