TLDR
From the stiffness method of structural analysis, both nodal displacements and forces are unknowns, and from this it is able to perform static condensation of a stiffness matrix without reordering the node-numbers of the system of equations, and thus the skyline profile is preserved.About:

The finite element method in engineering science
TL;DR: In this paper, the authors describe how people search numerous times for their favorite books like this the finite element method in engineering science, but end up in malicious downloads, and instead they cope with some infectious bugs inside their computer.

A frontal solution program for finite element analysis
TL;DR: The program given here assembles and solves symmetric positive–definite equations as met in finite element applications, more involved than the standard band–matrix algorithms, but more efficient in the important case when two-dimensional or three-dimensional elements have other than corner nodes.

Solution of linear equations with skyline-stored symmetric matrix
TL;DR: Fortran IV subroutines for the in-core solution of linear algebraic systems with a sparse, symmetric, skyline-stored coefficient matrix are presented and the application to ‘superelement’ condensation of large-scale systems is discussed.

Direct solution of large systems of linear equations
TL;DR: A very efficient computer subroutine for the direct solution of large numbers of simultaneous linear equations is presented, which uses Gauss elimination on positive-definite symmetrical systems to solve systems of very large size and bandwidth.
