Development of a methodology for the risk analysis of progressive collapse

Abstract

The existing regulatory approaches to design do not allow us to take into account the contribution of preventive design measures and design solutions to the reliability of the design. In certain cases, the risk assessment can be considered as a confirmation of the adequacy of engineering solutions used in the project to protect against progressive collapse. In the domestic and foreign regulatory framework, there are several normative documents that establish the rules for calculating the reliability of technical objects, requirements for methods, the procedure for presenting results, and defining fundamental approaches to analyzing the types, consequences, and criticality of failures of technical objects. In order to form a complete and developed system of regulatory documents, it is necessary to develop and implement a regulatory methodology for assessing the risk of failure of building structures, including working under special influences. The article considers a point-based system for determining the risk of structural failure, taking into account the features of various structural schemes of buildings, the possibility of several negative events.
