Quang Thang Do

Dear Manish Kumar Dubey

You may consider Euler's theory for buckling.

For example long column le/D > 12; Short column le/D

Abdelrady Okasha El-Nady

Dear Kumar Beam: For long beam you may use Euler beam theory. For short beam you may use higher order shear deformation theory. Shell: For thin shell (high R/h ratio) you may use membrane theory. For thick shell you may use higher order shear deformation theory.
