Vibration monitoring of joints of precast and cast-in-situ reinforced concrete

Abstract

Vibration monitoring of the defective and unimpaired constructors, in particular loop joints is carried out. The research of main dynamic informative parameters of technical state of structures of loop joints are submitted. Internal defects and changes in structures of joints of precast and cast-in-situ reinforced concrete are analyzed. Presented analysis based on determination of the frequencies of characteristic resonance oscillations using spectral method. Results of dynamic tests of beams with loop joints - diagrams of dependence of vibration displacement from frequency are presented/
