###### Abstract  
The continuous basalt fiber-reinforced polymer column filled with concrete (BFRPC composite column) can well resist the erosion of the external environment, improve the durability of the structure, and reduce the life-cycle cost of the project. To evaluate the mechanical behaviors of the BFRPC composite column under cyclic lateral loading, laboratory low-cycle reverse loading tests were implemented on a BFRPC composite column specimen, a prestressed reinforced concrete (PRC) tube column specimen, and a prestressed high-strength concrete (PHC) tube column specimen. The failure features, hysteretic curve, and skeleton curve for these three types of column specimens were compared and analyzed through the load-displacement hysteretic curve. The results indicated that the BFRPC composite column possesses the better bearing capacity and deformation performance. The horizontal bearing capacity of the BFRPC composite column is at least three times better than that of PHC and PRC tube columns. Finally, the functional expression of the skeleton curves for the BFRPC composite column is fitted by the rational function fitting method.

[PERSON] [23] studied the stress mechanism of FRPC composite columns. The results show that the fiber-reinforced polymer (FRP) tube can significantly improve the ultimate bearing capacity of the specimen. To study the flexural performance of FRPC composite column specimens, [PERSON] and [PERSON] [24] conducted four-point pure bending tests on several groups of different FRPC composite column specimens. The results show that the FRPC composite column specimen has good ductility, significant deformation before failure, and large residual load. [PERSON] and [PERSON] [25] investigated the vertical compressive capacity of FRP tube columns through experimental research and proposed a mechanical model under the action of axial compression. [PERSON] et al. [26] captured from an experimental study that the mechanical properties of FRP columns under hammering are similar to those of prestressed concrete columns. At the same time, many researchers studied the horizontal mechanical behavior of columns with different materials due to the importance of the horizontal bearing capacity for columns. [PERSON] et al. [27] studied the pile-soil interaction of glass fiber-reinforced polymer (GFRP) tube piles under the action of horizontal bearing capacity through full-scale horizontal bearing capacity experiments. [PERSON] et al. [28] implemented the low cycle pseudo-static tests on four PHC tube column models with various prestress levels to gain insight into their mechanical behaviors. [PERSON] et al. [29] deeply analyzed the mechanical properties of prestressed concrete beams by conducting low-cycle reverse load tests. [PERSON] et al. [30] conducted low-cycle repeated load tests on six fiber-reinforced polymer tube columns. They studied the horizontal bearing capacity and mechanical properties of carbon fiber-reinforced polymer (CFRP) tube columns and GFRP tube columns, respectively. The results show that the FRP material can significantly improve the horizontal bearing capacity, initial stiffness, and energy dissipation performance of the column. Among them, the improvement effect of CFRP material is better than that of GFRP material. In general, the existing research on the horizontal bearing capacity of FRPC composite columns mainly focus on fiber-reinforced polymer columns with carbon fiber, glass fiber, and aramid fiber as the reinforcement phase. However, due to the particularities of CBF materials, it is difficult to directly apply the existing research results to the design of tube columns containing CBF materials.
