This structure improves load-bearing capacity, stiffness, and seismic performance through the synergistic action of steel and concrete, making it suitable for high-rise buildings and scenarios with high seismic requirements. Construction involves addressing challenges such as the placement of reinforcement bars at beam-column joints and the dense arrangement of stirrups. Cruciform steel columns are commonly used core steel columns in steel-reinforced concrete structures.
