| Abstract: | Seismic properties and ductility of eighteen carbon fiber concrete columns reinforced with carbon fiber are carried on the numerical analysis by ANSYS.Those columns have been tested under low cyclic loading.We investigated the effects of axial compression ratio and horizontal carbon fiber reinforcement in the failure characteristics,the mechanical properties and failure mechanism of reinforced concrete columns.The tests showed that reinforcing concrete column with carbon fiber has a significant effect.What＇s more,hysteretic performance,seismic properties and ductility has been significantly improved. |
