Sažetak
This paper reports on original findings from advanced HYLSER-1 seismic tests conducted on steel-reinforced concrete column models subjected to simulated low and high axial loads. The study includes a comparative analysis of steel-reinforced concrete (SRC) column models and composite-reinforced concrete (CRC) column models, using refined nonlinear analytical micro-models. The results demonstrate that earthquake intensity, axial load level, and concrete confinement are the primary factors influencing the complex hysteretic responses and failure of column models reinforced with either conventional steel bars or novel glass fibre-reinforced polymer (GFRP) bars. These findings are crucial for enhancing the seismic design of alternatively reinforced columns subjected to severe earthquakes.
