| 摘要： | In the present study, a new fabrication method is proposed for concrete-filled hollow precast concrete columns (HPCC). In the proposed method, corrugated steel plates were used for the internal mold of the hollow core section to improve production efficiency and structural safety. To evaluate the constructability and structural performance, mock-up tests and cyclic loading tests were performed for four HPCC specimens and a conventional RC specimen. The test results showed that the overall behavior of the HPCC specimens was similar to that of the monolithic RC specimen, and the structural performances such as maximum load, initial stiffness, displacement ductility, and energy dissipation were comparable to or even higher than those of the RC specimen. The ultimate strength of the HPCC specimens agreed with the prediction by the current design code, which indicates that the proposed composite columns of precast concrete and cast-in-place concrete showed the full composite strength.
