Abstract: Using Moore-Penrose inverse theory,a set of formulations for calculating the static responses of a changed finite element structure are given in this paper.Using these formulations in struct ural analysis may eliminate the need of assembling the stiffness matrix and solving a set of simultaneous equations.
