Introduction to Finite Element Analysis of Hybrid Jute/Basalt Fiber Reinforced Polymer Confined UHPC Column under Axial Compression in Abaqus
Overview of the Study
Ultra-High Performance Concrete (UHPC) is known for its exceptional strength, durability, and ductility, making it suitable for high-performance structural applications. However, to further enhance its load-bearing capacity and ductility under axial compression, confinement using Fiber Reinforced Polymer (FRP) composites has been widely studied
Hybrid natural-synthetic FRP composites, such as jute/basalt FRP, offer a sustainable and cost-effective alternative to traditional synthetic FRPs (e.g., carbon or glass FRP). Jute fibers provide eco-friendliness and low-cost reinforcement, while basalt fibers contribute to high strength and stiffness. Combining these fibers in a polymer matrix can optimize the mechanical performance of confined UHPC columns

Finite Element Analysis (FEA) in Abaqus
Finite Element Analysis (FEA) using Abaqus/CAE provides a powerful numerical tool to simulate the axial compressive behavior of hybrid jute/basalt FRP-confined UHPC columns. This approach allows for
Material modeling of UHPC, jute/basalt FRP, and their interaction
Nonlinear analysis considering plasticity, damage, and large deformations
Validation of experimental results and parametric studies for optimization
Key Modeling Considerations
Material Properties
UHPC: Modeled using a concrete damage plasticity (CDP) model with high compressive strength and strain hardening/softening behavior
Jute/Basalt FRP: Defined as an orthotropic elastic material with different properties in fiber and transverse directions
FRP-UHPC Interface: Simulated using cohesive zone modeling (CZM) or surface-based contact to capture debonding effects
