Abstract
This paper introduces a newly proposed “loss factor function (LF)” and its application to bridge condition assessment based on the structure monitoring data. First, a viscoelastic model is integrated in the equation of motion of a beam. In this model, material characteristics contained two components such as elastic modulus and viscous coefficient. Viscoelastic model, different with linear elastic model, is nonlinear, and therefore, it reflects real state of the structure precisely. Secondly, LF is calculated from amplitudes and frequencies of power spectral density of random vibration signals and is concerned with mechanical parameters in detecting structural changes. Vibration of beams was investigated in case different random excitations are used to simulate ambient load in the process of varying material properties. Based on theoretical analysis and simulation result, this study reveals more effective in condition assessment of structure.
