Abstract

Abstract: In order to explore new applications for the regeneration of waste clay bricks and to expand the use of bamboo plywood in structural engineering, this paper proposes a novel type of GFRP-plybamboo panel tube dual confined recycled brick aggregate concrete ecological laminated column (abbreviated as GPR laminated column). Compression failure tests were conducted on 18 GPR laminated column specimens to investigate the influence of brick aggregate replacement ratio in recycled brick aggregate concrete (RBAC), GFRP tube thickness, sectional bamboo content, spacing ratio of pull rods, load eccentricity, and slenderness ratio on the compressive bearing capacity and deformation of specimens. The test results indicate that the compressive failure mode of GPR laminated column specimens is mainly characterized by cracks and local fractures along the winding direction of GFRP tube fibers, as well as crushing of the outer RBAC. The location of GFRP fiber damage shifts upward with the increase of GFRP tube thickness. When subjected to eccentric loading, the failure mode of the GPR composite column involves tension-side GFRP fiber fracture, and slenderness ratio exceeding 32, compressive-side GFRP fiber fracture is observed. The compressive load-bearing capacity decreases with the increase of brick aggregate replacement rate, constrain tensile rod spacing ratio, load eccentricity, and slenderness ratio. Additionally, the load-bearing capacity decreases with an increase in GFRP tube thickness, while the section bamboo content has no significant effect on the ultimate load-bearing capacity of the specimens. Finally, a calculation model for the ultimate compression bearing capacity of GPR laminated columns was established based on experimental results, which is expected to provide reference for the engineering application of the GPR laminated columns.

Key words: GFRP, plybamboo panel (PBP), recycled brick aggregate concrete (RBAC), compressive test, ultimate load-bearing capacity
