STRUCTURES WITH SYMMETRIES USED IN CIVIL ENGINEERING

Sorin VLASE, Călin ITU

Abstract


In many engineering application the designed device or product posses parts with some kind of symmetries. It is the case of automotive engineering or tools machines. We can find these type of symmetries too in the civil engineering. The existence of the symmetries leads to some properties that can simplify the vibrations calculus. In the paper are presented the main properties of a structure with transversal symmetry.

 Key words: symmetry, eigenvalues, eigenmodes, transversal symmetry
