| Abstract | ||
| This research presents an appraisal for Euler and Johnson theories based on experiment tests under compression dynamic buckling load. 20 specimens ( columns ) made from two materials, namely 1020 Hot Rolled and 5052 Aluminum alloy, are tested under compression dynamic buckling load. The following remarks can be concluded from the present work : 1- Euler ( for long columns ) and Johnson ( for short columns ) theories can be used to estimate the dynamic critical buckling load with design factor of 3 or more. 2- Initial deflection of column has an important effect on compression dynamic critical buckling load. | ||
