Seismic Behavior of Recycled Aggregate Concrete Filled Steel and Glass Fiber Reinforced Plastic Tube Columns
This paper presents the results of seismic tests on the recycled aggregate concrete filled steel tube (RCFS) and recycled aggregate concrete filled glass fiber reinforced plastic (GFRP) tube (RCFF) columns. The objective of this study is to evaluate the seismic behavior of steel/ GFRP tube in-filled recycled aggregate concrete (RAC) columns. The main parameters in the tests are the recycled coarse aggregate (RCA) replacement percentage and the tube material. The results show that both deformation and bearing capacities of RCFF and RCFS columns are greatly improved. The seismic behavior of RCFS columns is better than that of RCFF columns. Research findings also indicate that the energy dissipation capacity and the ductility slightly change with the variation of recycled coarse aggregate replacement percentage, whereas the bond-slip has little effect on the seismic behavior. Besides the experiments, a finite element method (FEM) analysis is also conducted. It is found that the seismic behavior of both RCFS and RCFF columns is decreased with the increase of the axial load ratio.
