Dynamic Isolation in Case of an Elastic Supported Viaduct
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
The dynamic modeling, aims to analyze the dynamic behaviour of the viaduct to external actions from the road traffic and / or seismic movements. The analytical expressions of pulsation, frequency and of the eigenvectors are presented, thus putting in evidence the influence of inertial and structural characteristics on these.

Internal Soundproofing Buildings Isolated by Elastomeric Links from Externally Induced Vibration
Interior soundproofing is a requirement for buildings with special activities where the level of vibration and noise shall be minimal. This paper specifies the essential requirements for the definition of performance vib...
Application of Superposition Principle to Detect Damages in Beams by using Natural Frequencies
This paper presents the researches made by the authors in order to detect damages in beams using natural frequencies by applying the superposition principle. The chosen type of beam was the cantilever one, for which a da...
Assessing the Sound Absorption of Micro-Perforated Panels by Using the Transfer Function and the Impedance Tube
