This paper presents numerical and experimental results of concrete columns reinforced longitudinally with basalt fiber reinforced polymer (BFRP) and steel bars as a composite system. The main objective is to reduce the number of steel bars replacing by BFRP bars under cyclic loading using open system for earthquake engineering (OpenSees). Moreover, to achieve the goal of this study, the parameter relationship of this system was measured in five bridge columns. One column was referred as a reference, and the other three with 17%, 33% and 50% of BFRP with steel amount of 83% 67% and 50% respectively was studied. Moreover, the main parameter was analyzed is the energy dissipation amount, hysteretic performance and residual displacements. The columns reinforced with BFRP were given the significant results in the studied parameters especially the columns reinforced with a high percent of BFRP compare to steel columns. |
