Abstract
Analytical stiffness matrices of different problems are modified in the light of incomplete modal data to reproduce the identified frequencies using different types of finite elements: a triangular plate element with 6 DOF/node, a 3D beam element and a brick element. The original characteristics of the stiffness matrix are retained after mofification. Unidentified modes are also changed to some extent due to stiffness modification.
