What is Geometric non-linear analysis of space frame with rotation greater than 90°, with Euler angles and quasi-fixed local axes system about?

The geometric non-linear analysis of space frames with deÿnition of the local axes through rotations similar to Euler angles, presents di culties when the rotations reach 90 • in the ÿxed local axes. To surmount these di culties this work presents a new technique using a system coined quasi-ÿxed local axes. In this technique, the direction cosines of these axes of the actual increment of loading are deÿned through the direction cosines of the moving local axes of the last iteration of the previous increment and of the quasi-ÿxed local axes of the previous increment (or ÿxed, in case of the ÿrst increment). The technique of deÿnition of the quasi-ÿxed local axes is used with updated Lagrangian reference. The numerical examples presented herein show the great numerical stability of the technique.
