Buckling of Guyed Towers
The buckling load of a column guyed in a plane by symmetric guy wires is considered. The column is built-in at the ground, supported at the top by guy wires, and is loaded by a vertical...
Interactive Buckling Analysis of Stiffened Shells Using Pregnant Sheel Elements
Two distinctive modes of failure dominate the failure of stiffened plates and shells, viz. the short-wave local mode and the long-wave overall mode. A new finite element technique which...
