Title of the articleEvaluation of the effectiveness of the use of high-modulus polymer composite reinforcement
Abstract.The interest of the enterprises of the construction industry in products made of polymer composite materials is growing every year. Along with the well-known advantages of polymer composite reinforcement, there are disadvantages that prevent its use in large-scale construction. The most characteristic disadvantage is the low modulus of elasticity compared to steel. This imperfection can be eliminated by using high-modulus polymer composite reinforcement in the structures. The purpose of the work is to evaluate the effectiveness of the use of high-modulus polymer composite reinforcement in bending elements. The objectives of the study are to assess the strength in normal sections of bent concrete beams reinforced with high-modulus polymer composite reinforcement, as well as to compare the bearing capacity of concrete beams reinforced with steel, low-modulus and high-modulus polymer composite reinforcement. Results. The paper proposes a comparative assessment of the increase in the ability of bending concrete beams in normal sections, reinforced with high-modulus polymer composite reinforcement, steel reinforcement and low-modulus polymer composite reinforcement. Conclusions. The significance of results obtained for the construction industry lies in the fact that the use of high-modulus polymer reinforcement increases the load-bearing capacity of concrete bending elements, while having a significant high elasticity compared to steel.
Keywords.non-metallic reinforcement, high-modulus polymer composite reinforcement, strength of normal cross-sections, concrete structures, bendable elements
