FIELD: civil engineering. SUBSTANCE: when measuring the initial stressed state of ferroconcrete construction fittings two toothings are formed at distance of anchoring length in crack origination zone. In one toothing resistance strain gauges are installed on fittings and in the other, fittings are cut off. This done, concrete layer is opened in succession till fittings between toothings are exposed, and stressed state of fittings is measured after each opening of concrete. Final measurement is performed after two toothings are combined into one toothing. Resistance strain gauges may be positioned on fittings antipodally. EFFECT: higher measurement results. 2 cl, 1 dwg
