| Abstract | ||
| This research investigated the cyclic behaviour of fully encased composite (FEC) columns. By constructing and investigating thirty-six FEC columns to increase the strength and performance of composite columns subjected to combined axial and cyclically increasing lateral loads. The goal of this research is to investigate the effect of the axial load ratio and concrete reinforcing bars on the behaviour of composite columns subjected to combined axial and cyclically increasing lateral loads. Finite element analysis was performed on each specimen, taking into account the inelastic behaviour of concrete, structural steel, and longitudinal and transverse steel bars. In this research, the finite element models created in ANSYS software were verified and calibrated against previously published experimental results. FEC columns are studied in terms of hysteretic performance, load-carrying capacity, energy dissipation capacity, ductility, and stiffness degradation. The composite columns provide an interesting result in the numerical simulation. | ||
