Influence of static long-term loads and cyclic freezing/thawing on the behaviour of concrete beams reinforced with BFRP and HFRP bars

Abstract

Abstract.The purpose of this study was to define the influence of static longterm loads and cyclic freezing/thawing on the deflections and cracking of concrete beams with non-metallic reinforcement. The rods made of basalt fiber reinforced polymer (BFRP) and hybrid fiber reinforced polymer (HFRP) were used as non-metallic reinforcement. Four series of single span beams were loaded with a single static force in a three-point bending test, then specimens were subjected to 150 freezing/thawing cycles in a large-size climatic chamber. The experimental test results were compared to those obtained from prior carried out short-term tests and theoretical calculations based on ACI 440:1R-06 standard concerning concrete element with non-metallic reinforcement.

Shear Behavior of Concrete Beams Reinforced with a New Type of Glass Fiber Reinforced Polymer Reinforcement: Experimental Study

“…Corrosion of reinforcing steel is the main factor causing material degradation in reinforced concrete structures, which, if exposed to particularly adverse environmental conditions, cease to meet the requirements of durability and reliability in a facility in a relatively short time [1][2][3][4]. The durability of reinforced concrete structures is particularly important for industrial facilities [5][6][7].…”
