Part of: Probabilistic Mechanics and Structural and Geotechnical Reliability


A more accurate technique which can be applied for reducing the order of system matrices when employing the finite element method (FEM) is presented. Unlike traditional reduction techniques, principal degrees of freedom are automatically selected. The results are verified by an example and in good agreement with those obtained from system matrices of without reduction.
