КРИТЕРИИ ДЛЯ ОЦЕНКИ КАТЕГОРИИ ТЕХНИЧЕСКОГО СОСТОЯНИЯ ЖЕЛЕЗОБЕТОННЫХ КОЛОНН, РИГЕЛЕЙ, БАЛОК И ФЕРМ

Abstract

The article considers the process of formation of evaluation criteria in the course of operation of the category of technical condition of reinforced concrete columns, crossbars, beams and trusses. Criteria for limited serviceability and emergency conditions were determined using calculations using the method of limiting forces, taking into account the bearing capacity reserves laid down in the design. As an example, one characteristic design defect for each type of structure is considered. The establishment of criteria for defects that were not considered in the calculations was carried out by analyzing and studying the characteristic defects of building structures of buildings and structures based on data from previous studies, as well as based on the results of consideration of other regulatory and technical documents. The criteria given in the final table were proposed for inclusion in the second edition of the revision of GOST 31937–2011 «Buildings and constructions. Rules of inspection and monitoring of the technical condition».
