Investigation of the influence of local stiffness modification is a currently relevant engineering topic. The literature is limited to studies on the influence of the damage that is introduced into a computational model as a reduction of the elasticity modulus in the part of the structure where the damage occurs. The paper presented considers the influence of various local changes (a crack, a change of mass, a change of cross section) on eigen-vectors. These vectors are separated into three direction components (longitudinal and transverse displacements and rotations). In the presented studies, longitudinal displacements are also considered since these components are neglected in the studies in the literature, although they offer significant conclusions about the change of the eigen-vectors. The comparison of the eigen-vector change for the various types of modifications clearly shows that some principles exist from which it would be possible to determine the location and type of structure change. The magnitude of the change must be further determined by other conventional methods. The introduction of the longitudinal displacements indicates that the type and location of the structure change can be estimated on the basis of the specific deformation changes which belong to the eigen-vectors.
