In this paper, the layer-by-layer integration method was used to analytically establish and investigate the axial load-bending moment (P-M) interactions of geopolymer concrete (GPC) columns reinforced with and without steel fibers. The developed analytical model was validated with experimental results. The developed analytical method provided reliable estimates of the maximum axial load and bending moment capacities of GPC columns reinforced with and without steel fibers. A parametric study was also conducted to investigate the influence of the compressive strength of GPC, longitudinal steel bar reinforcement ratio, and aspect ratio of steel fibers on the P-M interactions of GPC columns.
