Comparative Modal Analysis of a Rigid Structure with Conservative Insulation
MetadataShow full item record
This paper deals with dynamics of compact rigid structures with elastic insulation and subjected to various vibratory, shock or seismic actions. It was supposed a simple rigid model with six degrees of freedom, affected by one or both vertical symmetry planes. Modal analysis was performed for six different rigidity cases. Concluding remarks dignify the correlation between isolation characteristics and natural pulsation in terms of eigenvalues and eigenvectors.
