Abstract

In this study, flexural behavior of hybrid reinforced concrete beams were investigated theoretically and by the finite element method. Within the scope of the study, beams with identical geometry and concrete compressive strength; designed as having different reinforcement ratios. The results obtained from the theoretical work and finite element method were commentated by using load-displacement curves, load carrying capacities and strain indices. The effects of the fibrous polymer / steel ratio (Af / As) on the stiffness, strength and midpoint displacement of the beams were investigated. In addition, the effects of reinforcement ratio on load carrying capacity and deformability indexes were investigated.

Abstract

Bu çalışmada hibrit donatılı kirişlerin eğilme davranışları teorik olarak ve sonlu eleman yöntemi ile incelenmiştir. Çalışma kapsamında özdeş geometri ve beton basınç dayanımına sahip kirişler; farklı donatı oranına sahip olacak şekilde tasarlanmıştır. Teorik çalışma ve sonlu eleman yönteminden elde edilen sonuçlar yük-yer değiştirme eğrileri, yük taşıma kapasiteleri ve şekil değiştirme indeksleri kullanılarak yorumlanmıştır. Lifli polimer/çelik oranının (Af/As) kirişlerin rijitliği, dayanımı ve orta nokta deplasmanları üzerine yaptığı etkiler incelenmiştir. Ayrıca donatı oranının yük taşıma kapasitesi ve şekil değiştirme indeksleri üzerine etkileri araştırılmıştır.
