This paper presents a procedure for modal reanalysis of structures with topological modifications. The procedure is based on the results of initial modal analysis of the original structure. It is necessary for topological modifications with the increase of joints and the number of degrees of freedom. The research results show that the proposed method is effective and easy to implement on a computer
