Modal Analysis of the Viaducts Supported on the Elastomeric Insulators within the Bechtel Constructive Solution for the Transilvania Highway
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2012, Vol 9, Issue 2
Abstract
The article presents an approach of six degrees dynamic model of a rigid-solid with some types of symmetries. These symmetries lead to simplified mathematical models, which are easier to solve. If the rigid-solid is jointed of the structure by four elastic bonds, the mathematical model becomes still simple and the vibrations are decoupled into four subsystems of movements: side slipping and rolling, forward motion and pitching, galloping motion, gyration. There is also a case study: the modal analysis of a bridge with the total length of 200 meters, 13.2 meters width and 2.5 meters height, modeled as a rigid solid supported elastically for the Transilvania highway.
