The subject of study - time frequency response of vibro-acoustic emission signals and defect induced oscillations. Purpose - to increase reliability and reduce labor costs during surveys reinforced concrete bridges and overpasses. The method of investigation - a digital oscilloscope signals and construct the spectral characteristics. The method for detection of defects in the event of typical reinforced concrete beam bridges for acoustic emission signals in the spectrum of noise, equipment fixing vibroacoustic signal spectra and emission specifications and instructions for its use. Application - the establishment of the technical condition of reinforced concrete bridges and overpasses.5481 Product Description popup.authors Єрьоміна Віра Іванівна Оксень Євген Іванович Оксень Дмитро Євгенович Яковлева Надія Самсонівна popup.nrat_date 2020-04-02 Close
