Increasing demand for high precision mechanical components has increased the importance of dynamic design of structures. Competitiveness dictates the necessity to predict the dynamic properties of structures when some modifications are to be made. This paper presents a new structural reanalysis approach which is an extension of Successive Matrix Inversion method presented for static analysis to dynamic analysis of structures. The method is based on exact calculation of Frequency Response Function (FRF) matrix of a modified structure using FRF matrix of the original structure and modifying mass, stiffness and damping matrices. Case studies are presented in order to demonstrate the application of the method. The results obtained are compared with exact values, as well as with those obtained by using Özgüven’s Structural Modification method.
