FIELD: fire fighting, particularly to provide fire safety of buildings and building structures.
SUBSTANCE: method to perform tension member tests without member destructing to determine simple quality indicia and to estimate indicia values by means of static check involves settling above simple quality indicia; determining basic load values and load stress intensity in main reinforcement and determining fire-resistance rating of tension members from nomographic chart.
EFFECT: increased reliability of static check and non-destructive tests.
