Columns are essential part of several civil engineering applications that relocate the weight of the superstructure and the other loads to the soil. Usually, columns are subjected to eccentric compressive loads. Sometimes, it is required to increase the cross-sectional area of columns to gain additional load capacity. This paper investigates the behavior of reinforced concrete columns under uniaxial loading. Five specimens of 0.2 × 0.2 × 1 m were fabricated to study the effect of type of concrete and near surface mounted NSM strengthening technique on the structural behavior of the columns. All columns were tested under uniaxial loads of 50 mm offset with simply supported ends. The presented strengthening techniques are flexible and effective. The experimental results showed that using of steel fiber concrete SFC of 1% volume fraction raised the ultimate load by 200% while increasing of concrete strength by 42.1% achieved just 36.4% additional load capacity. Also, strengthening of columns using NSM steel and carbon fiber reinforced polymer bars increased the load carrying capacity by 54.5 to 136.4%. Furthermore, the stiffness criteria increased by 105.3, 29.3, and 90% for the specimens with higher compressive strength, SFC, and strengthened with NSM steel bars owing to the additional stiffness provided. However, the brittle weakness nature of FRP composites in compression decreased the stiffness criteria by 14.6%.

et al. 2023

View full text Add to dashboard Cite

In civil engineering, carbon fibre-reinforced polymer (CFRP) composites have emerged as a promising alternative to conventional materials. The article provides a comprehensive overview of the application of CFRP composites in various building structural elements and their characteristics and properties, such as their fatigue and corrosion resistance, stiffness and high strength, and incorporation of temperature factors. The advantages and disadvantages of CFRP composites and the current trends and prospects for CFRP composites in the construction sector are discussed. In addition, the article compares various studies on CFRP composites to shed light on their performance and potential limitations. This paper aims to provide useful information to researchers and practitioners interested in using CFRP composites in civil engineering applications. In addition, the article discusses emerging materials in CFRP, such as nanostructured carbon fibres, hybrid fibre reinforcement, and self-sensing CFRP. Additionally, the paper outlines how CFRP composites promote sustainability by increasing structural durability and longevity.
