Computational Assessments on Transversal Vibration of Large Beams due to Impulsive in-Motion Actions
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
This study deals with the area of condition monitoring and dynamic damage detection in composites based structural parts embedding insulation systems. The paper contains a briefly presentation of some particular and inadequate aspects performed by computational technique, regarding ordinary behaviour a large reinforced concrete beam subjected to impulsive and mobile loads during the exploitation time. A set of appropriate characteristics of deck bridges has adopted. The computational model in this paper has developed taking into account some particular aspects regarding the structure response of the impact tests applied on deck bridges in view of the dynamic characteristic evaluation and the structural damage level characterization. Advanced computational techniques for signal processing (Power Spectral Density, Short Fourier Transform, and Cepstrum) has used. Concluding remarks dignify the qualitative differences between the simple and the realistic approaches of dynamic perturbations in respect with the truck – obstacle – beam interactions.
