Abstract

The aim of this review paper is to summarize available reports, papers, theses, dissertations and conference papersdealing with the performance of aluminum-concrete composite columns. Hollow aluminum sections filled with concrete have been used as composite columns due to their corrosion resistance, easy production, appearance and lightweight. Many researches were performed in the area of concrete-filled hollow sections (tubes). However, there are few researches have been performed on concrete-filled aluminum tubes. In this review, different available published papers are summarized to view the type of the studied aluminum-concrete columns and the main studied parameters that affecting the behavior of these composite columns. More than (190) specimens are collected and showed in this review.

ان الهدف من مقال المراجعة هذا هو تلخيص التقارير والبحوث والرسائل والاطاريح وبحوث المؤتمرات التي تعاملت مع سلوك الاعمدة المركبة من الخرسانة والالمنيوم. لقد اُستخدمت مقاطع الالمنيوم المجوفة المملوءة بالخرسانة كأعمدة مركبة نظراً لمقاومتها للتآكل وسهولة انتاجها ومظهرها وخفة وزنها. هناك العديد من البحوث التي اٌجريت عن موضوع المقاطع المجوفة المملوءة بالخرسانة، ومع ذلك فقسم قليل منها قد اُجري عن مقاطع الالمنيوم المجوفة المملوءة بالخرسانة. تم في هذه المراجعة تلخيص مختلف البحوث المنشورة والمتوفرة عن هذا الموضوع وذلك لبيان نوع أعمدة الالمنيوم-الخرسانة المدروسة والمتغيرات الرئيسة المؤثرة على سلوك هذه الاعمدة المركبة. وقد تم جمع وعرض أكثر من (190) نموذج في هذه المراجعة.

Abstract

Hybrid double skin tubular members (DSTMs) arecomposite section of three material FRP tube outside,steel tube inside and concrete sandwiches in between. Thecurrent study investigated the behavior of fourteencircular DSTCs under axial load. Every specimen isaverage of a pair of samples, the key parameters are thelayers of outer carbon FRP tube, the compressive strengthof concrete and the types of columns include (DSTC) andconcrete filled FRP tube (CFFT). The test results showthat the concrete has effected constrained between twotubes, that’s leads to increases strength and ductility ofcolumn, the most effective parameters has the number oflayers of outer FRP tube the stress-strain relationshipshows high ductile behavior of under compression testand the CFFT is superior in ultimate load compared withDSTC.
