Abstract

Çekme testi, geleneksel çelik donatıya alternatif olarak kullanılan Cam Elyaf Takviyeli Polimer (GFRP) çubukların Mekanik özelliklerin değerlendirilmesinde kritik bir rol oynamaktadır. GFRP çubuklar için test standartlarının geliştirilmesi için yapılan araştırmalar önemli bir aşamaya gelmiş olmasına rağmen, çelik donatıların testlerine kıyasla, bu testlerin uygulanması genellikle daha çok sayıda numune ve özel ekipman gerektirmektedir. GFRP çekme testleri için bu çalışmada, çelik donatılar için kullanılan mevcut test ekipmanlarının kullanıldığı yeni bir yöntem önerilmektedir. Geliştirilen bu yenilikçi yaklaşım, GFRP takviye elemanlarının mekanik özelliklerinin değerlendirilmesi için pratik ve maliyet-etkin bir çözüm sunmaktadır. Bu test yöntemi, GFRP çubukların betonarme yapılarda daha yaygın olarak kullanılmasını kolaylaştırarak verimliliği artırmayı ve sürdürülebilir inşaat uygulamalarının ilerlemesine katkıda bulunmayı hedeflemektedir.

A NEW APPROACH TO TENSILE TESTING OF GFRP BARS

Abstract

Tensile testing is a critical procedure for evaluating the mechanical properties of Glass Fiber Reinforced Polymer (GFRP) bars, which emerged as an alternative to traditional steel reinforcement in reinforced concrete structures. While significant research has led to the development of testing standards for GFRP bars, their implementation often necessitates additional specimens and specialized equipment compared to their steel counterparts. This study proposes a new method for conducting GFRP tensile tests using standard equipment designed for conventional structural steel rebar testing. By employing existing devices, our approach offers a practical and cost-effective solution for assessing the tensile properties of GFRP reinforcement. This simplified testing method aims to enhance efficiency, facilitate wider adoption of GFRP bars in reinforced concrete structures, and contribute to the advancement of sustainable construction practices.
