초록

A segmental concrete-filled basalt fiber-reinforced polymer (BFRP) tube was proposed, whose lightweight characteristic promoted convenient bridge column transportation and construction. A special connecting component between the adjacent BFRP segments ensured effective transfer of sectional forces. Four specimens, including three segmental specimens and one comparative integral concrete-filled BFRP tube, were tested to investigate the mechanical performance of the BFRP tube under cyclic loading. Damage patterns, load-deformation response, and strain development were observed, showing that the segmental concrete-filled BFRP tube presented satisfactory load-carrying and deformation capacities. Further, the connecting component effectively guaranteed a satisfactory hysteretic performance. Based on the test results, the overall load-carrying capacity was mainly determined by the moment resistance of the interface. Furthermore, the segmental structure weakened the confining effect on the core concrete, though applying multiple stirrups could compensate for the reduced confining effect. Finally, design methods were proposed for the connecting component.
