Peak Strength Expression for Concrete Confined with Fiber-Reinforced Polymer
Publication: ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part A: Civil Engineering
Volume 4, Issue 3
Abstract
This study obtains a three-dimensional unified peak strength expression for confined concrete from the reported experimental results of circular concrete columns confined with different fiber-reinforced polymer (FRP) materials under axial compressive load for application in pile design. The reported experimental results are divided into two groups: FRP-wrapped and FRP tube–encased specimens. An assessment using various statistical indicators is carried out to evaluate the performance of existing predictive equations for peak strength. A reliability analysis of the models is conducted using the advanced first-order second-moment approach. Based on the assessment, it is inferred that most of the models conform to the reliability index criteria suggested by current requirements for structural concrete.
