A Study of Quality Management in Construction

Abstract

Numerous criteria affect the efficacy of FRP couplings on circular and square concrete columns, and the objective of this work is to explore how tiny FRP concrete columns behave when subjected to axial pressure loading. Design, technique, and strategy as an example, these factors include the browser's form (circular or rectangular), the core's size, and the number of layers of FRP (1–3). Other elements include concrete strength (low, normal, and high), FRP type (carbon or glass), and the number of square columns. The suggested equations and the present experimental findings show a good correlation. As the average hoop strain in FRP wraps at rupture might be lower than that determined by tensile coupon testing, the assumption that the FRP-contained concrete cylinder ruptures at its maximum tensile strength is not valid. Using the effective hoop rupture strain composite materials, the effective peak strength and strain formula for FRP concrete restricted columns must be based on this observation.
