An appraisal of euler and Johnson buckling theories under dynamic compression buckling loading

الملخص EN

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.
