Numerical Analysis of Delamination of High-Performance Concrete (HPC) Strengthened Reinforced Concrete (RC) Beam

Abstract

Abstract This study investigates the numerical analysis of delamination behavior of high-performance concrete (HPC) strengthened reinforced concrete (RC) cantilever T-beam by using finite element method. A length of 1000 mm reinforced concrete cantilever T-beam and height of 1600 mm reinforced concrete column will be created. Besides that, the truss members such as the stirrups and the rebars will also be added into the structure as a reinforcement. The HPC layer will be assigned on the top of the cantilever T-beam as a coating material. The study is to investigate the influences on the delamination behavior when the thickness, width, and coefficient of friction of the HPC layer has been applied on the model as a coating material. Finite element model (FEM) will need to be created and justified in ABAQUS software before applying the parameters for analysis. Limited studies had been conducted on the delamination behavior of using HPC layer as a strengthening mechanism and analyze the output such as the COPEN and SDEG. Based on the results extracted from the software, the delamination behavior can be observed and analyzed and investigate the influence of difference parameter has been assigned. Therefore, this research paper will analyze the influence of the layer thickness, width of the layer, and the coefficient of friction between the substrate and the layer.
