Dynamic analysis of structural systems using component mode synthesis

The major issues related to the analysis of large structural systems by substructuring are investigated in the present paper. The effectiveness shown by the component mode synthesis method with reference to other approaches is discussed. Such method is more appropriate when the whole structure is designed in such a way that major parts with different structural properties and characteristics are present, like in the case of structural systems composed by a primary and a secondary substructure. Moreover three different component mode synthesis method, in the case of structural systems composed by two substructures, are described.
