Formulation Of The
Total Potential Energy Functional For A Thin- Walled Box Column Applicable To Raleigh- Ritz Method
This work is concerned with the formulation of the Total Potential Energy Functional for a Thin -walled Box Column. Specifically, the formulated Energy functional supports the use of Raleigh - Ritz Method – RRM (with polynomial shape functions) in the stability analysis of thin-walled box (closed) columns. The formulated energy functional took its derivative origin from the basic elasticity theories,
