Behavior of Steel-UHPC Composite Column Under Axial and Flexural Loading
The most important and most frequently encountered combination of construction materials is that of steel and concrete, with applications in multi-story buildings and constructions. The combination of concrete and steel utilizes the compressive strength of concrete and tensile capacity of steel and the resulting composite members offer many structural as well as economic benefits. The recent development of concrete technology resulting in a new type of concrete with many advanced properties, it is called in common name Ultra High Performance Concrete (UHPC). By substituting UHPC to Normal Concrete, the resistance of concrete materials could be reached the resistance capacity of steel and consequently, obtaining optimal load caring of each contribution material. The replacement does not only increase the stiffness and overall ultimate strength but also reduces the cross-section of the composite beams. Furthermore, the need for economical alternatives for steel-normal concrete composite structure and faster construction processes during the erection of structures, boost the investigation in the domain of steel- UHPC composite construction. This study presents a numerical simulation to investigate the structural performance of steel-UHPC Composite Column under axial and flexural loading. Non-linear finite element analysis was conducted, which uses the Concrete Damaged Plasticity (CDP) model. The numerical results of the proposed model showed a good agreement with the experimental result to capture the behavior of steel-UHPC composite column under axial force and bending moment.
