Abstract


The progressive collapse estimation  and the ways of their prevention are highly depends  on the decisions  of the failure criteria of elements and based on the calculation methods. The aim of the article is to cover issues of progressive collapse modeling using modern software systems, estimation of their failure criteria, comparison and identification of features taking into account the possibility of their use in solving various  tasks  classes.  The main objectives of the study  is  to examine the criteria of element failures in emergencies used in a variety of software systems; comparative calculation of the steel frame with single element failure; assessment of the possibility of using different approaches and software systems in the structural safety analysis of buildings and structures.  Methods.  Methodology of the  tasks  solving is based on the  numerical studies of steel frame  after one column  failure calculated using  SAP2000 software systems and Extreme Loading for  Structures (ELS).  Results.  The analysis of elements nonlinear behavior and criteria for their failure in emergency situations calculated using two different software systems are showed. This article shows a comparative analysis of the progressive collapse scenarios  of the steel frame derived from non-linear analysis using various modeling methods. The studies indicate the convergence of  various software systems using for progressive collapse scenarios search. Scientific novelty.  The different software systems and their methods of calculation buildings and structures in emergency situations were studied. The software  selection  criteria  of  the  application for solving various  tasks  classes  were obtained.  These criteria  are associated with the analysis of the structural safety of existing and new buildings.  The practical significance.  Examination of the various progressive collapse modeling methods of buildings and structures  opens  the way to a better understanding  of a  ensuring important  building  objects  vitality  problems  and  makes possible  to  create  a  rational design  solutions  to  protect  buildings  against progressive collapse. These results allow us to make an informed decision about application of software complexes depending on the purpose of the calculation.
