Research ArticleOpen accessIn the abstractDynamic Solution Code for Structural Analysis upon Joint ElementS. A. Sadrnejad, M. LabibzadehThe analysis of large structures mostly requires a complete three dimensional finite element discretization. Stability of such structures includes not only the stability of structure itself but also that of foundation as well as interconnection elements. The general instability of a structure may be affected by two aspects, firstly, an inappropriate preliminary classical design of the structure and inadequate control … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,446 accessesView PDF Cite
