| Abstract [eng] |
Reinforced concrete structures are probably the most common ones in the world, however, problems frequently arise due to the corrosion of steel reinforcement, this phenomenon occurs especially when concrete structures are placed in an aggressive environment. In recent decades, the world's scientists and engineers are constantly looking for innovative and cost-effective solutions to this problem. One of the solutions to this problem is the use of polymer composite reinforcement in concrete structures. The aim of this paper is to determine the usability of the composite reinforcement in the elements subject to eccentric compression. The paper presents the types of the polymer composite reinforcement, their mechanical and physical features, describes the impact of obsolescence and environmental conditions on the features of polymer composite reinforcement. The research work includes bearing capacity comparable calculations of an element subject to eccentric compression, reinforced by steel and fiberglass polymer composite reinforcement bars, when the element is loaded by axial force and bending moment. An overview of prices of polymer composite and steel reinforcement bars is presented. |
