In this tutorial, the Simulation compression test of CFRP composite spirals in circular hollow UHPC columns in Abaqus has been done. The Ultra-High-Performace-Concrete column is modeled as a three-dimensional solid part. The spiral CFRP part is modeled as a solid part, the longitudinal steel bar is modeled as a wire part. You can see a figure of the assembled parts below
Hollow ultra-high-performace-concrete columns (UHPC) are preferred to be used for ground piles, utility poles, piers with medium–low height, and piers of tall bridges due to their higher resistance to axial loading and bending moments, superior structural efficiency, higher stiffness to mass and strength to mass ratios, lower self-weights, and economic designs as compared with the solid concrete columns.R ecently, carbon fiber reinforced polymers (CFRPs) have been used as longitudinal and transverse reinforcements in hollow and solid concrete columns
The Concrete Damaged Plasticity is used to model UHPC column under the compression load. The CFRP spiral part is defined as an elastic member. The elastic-plastic model is selected for the steel bar. The dynamic explicit step with a specific time, and prefect contact between the rigid bodies and column is considered. The CFRP and steel bars are embedded inside the UHPC column. The proper boundary conditions and mesh are assigned to the all parts
After the simulation all results such as stress, strain, damage, failure, force-displacement diagram,… are available. You can see some figures for the results below
