N2 - Stiffness matrices for complete structures, or for structural components, may be derived using numerical techniques, such as the finite element (FE) method, or using experimental procedures. Inevitably there are associated errors. This paper describes a technique for adjusting the terms of such matrices to minimize the errors and ensure compliance with symmetry and equilibrium requirements. Consideration is limited to the linear elastic structures.
