| Abstract: | The effects of spiral bars on the mechanical properties of prestressed high performance concrete (HPC) tube pile are analyzed. It is verified through experiments and theoretical calculations that the spiral bars significantly increase the member's strength, plasticity, ductility and anti-seismic capability. And calculation formula are inferred, which make it convenient for tube piles design and research. |
