Concrete-filled steel pipe columns are structural members formed by filling concrete in steel pipes, where both the steel pipe and its core concrete work together to bear external loads. Available in various cross-section forms including circular, square, rectangular, and polygonal configurations.

This innovative combination leverages concrete's high compressive strength with steel's superior bending resistance and elastoplastic properties, creating a composite material where the concrete is placed under lateral compression, effectively doubling its compressive capacity.
