Abstract AR
البحث الحالي يعرض تقييم لنظريتي أويلر و جونسون معتمدا على الفحوصات العملية تحت الأحمال الانبعاجية الضغطية الحركية.
عشرون عينة (أعمدة) صنعت من مادتين ھما الفولاذ 1020 Steel Alloy Hot Rolled و سبيكة الألمنيوم Aluminum Alloy 5052 و فحصت تحت الأحمال الانبعاجية الانضغاطية الحركية.
النقاط التي استنتجت من البحث الحالي ھي : 1- نظريتي أوير (للأعمدة الطويلة) و جونسن (للأعمدة القصيرة) يمكن استخدامھا في تقييم الحمل الحرج الانبعاجي الانضغاطي الحركي مع عامل تصميمي بمقدار 3 أو أكثر.
2- الانحراف الأولي للعمود له تأثير مھم على الحمل الانبعاجي الضغطي الحركي.
Abstract 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.
