Finite Element-Based Performance Analysis of Encased Composite Columns under Monotonic Axial Compression Load

This paper presents the results of an investigation into performance fully encased composite columns under monotonic axial load using finite element simulation. The damage characteristics and specimen were mainly focused on influence compressive strength concrete size reinforcement. material was modeled plasticity (CDP), which incorporates hardening softening behaviors, steel metal plasticity. obtained from current study validated by previously conducted experimental work manual calculation based Eurocode 4. According to FEA result, matrix significantly minimized with increase in concrete. By keeping other parameters constant, longitudinal reinforcement diameter minimizes equivalent plastic strain both structural bars. Furthermore, showed that numerical simulation fairly analytical solution.
