methods of destructive testing of structural full-scale members length. SUBSTANCE: method consists in local loading of structural members, determination of values of change of nominal parameters of structural member state in tested zones, registering of information by corresponding flaw detection methods and determination of changes of extreme local parameters of state of structural members near defects detected in tested zones of structural members. Then values of changes of extreme local parameters of state of structural members are determined by extrapolation, and maximum values of parameters of state of structural members are found as a sum of respective nominal parameters of state of structural members and values of changes of extreme local parameters of state of structural members, and obtained maximum values of parameters of state of structural members are compared with permissible values. EFFECT: higher accuracy of evaluation of residual strength of structural full-scale members. 7 cl, 1 dwg
