Abstract

ABAQUS software was used in a finite element analysis (FEA) to analyze the behavior of composite precast concrete beams the behaviour of composite precast concrete beams, ABAQUS software was used in a finite element analysis (FEA). This study aims to present a model that can be used to analyze composite precast concrete beams with finite element techniques. Concrete is a widely used material in civil structures and many architectural, and it behaves differently in compression and tension as well as nonlinearly elastically. Concrete's characteristics make it challenging to model or simulate the substance. An issue with the bond-slip relationship between concrete and steel in reinforced concrete is particularly problematic. However, certain presumptions were made in this study, such as the perfect bond between the steel and concrete and the concrete damage plasticity (CDP) model for concrete properties, when performing the finite element analysis for composite concrete beams through ABAQUS simulation. When comparing analysis and experimental results, simulated tensile deformations closely resemble the actual crack patterns found in tests. The crack pattern is provided by a finite element model that exhibits the same trend in the load-displacement relation as the experimental ones.
