Abstract

Penelitian ini bertujuan untuk menguji sejauhmana FRP tube yang terbuat dari Carbon Fiber Sheet efektif digunakan sebagai material perkuatan kolom beton ringan pada saat kolom tersebut dibebani secara tekan sentris. Sejumlah delapan buah silinder beton ringan dengan ukuran diameter 150 mm dan tinggi 300 mm dicetak dan dites hingga hancur. Kedelapan silinder tersebut terdiri dari dua buah silinder tanpa perkuatan, empat buah silinder dengan perkuatan menggunakan FRP tube, dan dua buah silinder dengan perkuatan menggunakan FRP wrapping. Hasil penelitian ini tidak dapat menunjukan sejauhmana FRP tube maupun wrapping efektif digunakan untuk memperkuat beton ringan karena benda uji miring. Walaupun demikian, tampak bahwa FRP tube dengan 3 lapis sangat efektif untuk memperkuat beton ringan Karena itu, untuk mengatasi masalah kemiringan pada benda uji yang diperkuat dengan FRP tube, perlu digunakan bekesting pada saat pengecoran.

Abstract

This article presents the results of a research project that aimed to evaluate how the number of fiber-reinforced polymer (FRP) layers and the compressive strength of concrete affect the stress-strain behaviors of concrete columns produced from artificial lightweight aggregate with square cross-sectional shapes. Eighteen test specimens were manufactured and wrapped with glass fiber-reinforced polymer (GFRP) material. The specimens were later subjected to concentric compression for experimental evaluation. The experimental results suggest that GFRP efficiently confines square lightweight aggregate concrete columns. Furthermore, the test results indicate that adding FRP layers augments the ultimate stress and strain. Finally, the results suggest that an increase in the compressive strength of concrete leads to a corresponding increase in the ultimate stress. On the other hand, it has been observed that the ultimate strain decreases as compressive strength increases. The research findings reveal the behaviour of FRP-confined square lightweight aggregate concrete columns, which may also be utilized to formulate a new design-oriented model for these columns.
