Vibration monitoring of building constructions

Abstract

Vibration monitoring of the defective and unimpaired constructions, in particular beams with loop joints and elements of brickwork with concrete inclusions are carried out. The research of main dynamic informative parameters of technical state of structures of loop joints and elements of brickwork 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 building constructions - diagrams of dependence of vibration displacement from frequency are presented.
