چکیده
This study discusses the behavior of ambient-cured circular geopolymer concrete specimens tested under different loading conditions. Twelve were cast and to investigate influence type reinforcement, that is, steel glass fiber-reinforced polymer (GFRP), pitch transverse conditions (concentric axial load, 15 35 mm eccentric four-point bending). The load carrying capacity, confinement efficiency, deformability decreased for replacement reinforcement with same amount GFRP concentric loads. However, reinforced (RC) specimen was higher than its counterpart bending. Overall, reduction in helices GFRP-RC resulted a significant improvement deformability, postpeak behavior, load–bending moment capacity Moreover, theoretical equations based on pressure provide accurate predictions load-carrying columns bars helices.

Workshop Presentation Infrastructure Applications of Frp Composites Behaviour of High Strength Concrete Columns Reinforced with Gfrp Bars and Helices under Different Loading Conditions
The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...

This paper provides a review of some of the progress in the area of fiber reinforced polymers (FRP)-strengthening of columns for several loading scenarios including impact load. The addition of FRP materials to upgrade deficiencies or to strengthen structural components can save lives by preventing collapse, reduce the damage to infrastructure, and the need for their costly replacement. The ret...

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...
متن کاملExperimental and Numerical Study on Bar-Reinforced Concrete Filled Steel Tubular Columns Under Axial Compression
The behaviors of bar-reinforced concrete filled steel tubular columns subjected to axial load were studied. One plain concrete filled steel tubular column and three bar-reinforced concrete filled steel tubular columns were tested. The deformation of specimens and the strain of steel tubes were measured. Based on experimental researches, a simple numerical analysis method was presented to simula...
