摘要
通过ANSYS试验对18根低周反复荷载作用下碳纤维布加固混凝土柱的抗震性能和延性进行数值分析。探讨了轴压比、碳纤维围束加固量对加固钢筋混凝土柱的破坏特征、受力性能及破坏机理的影响。试验表明,碳纤维布加固钢筋混凝土柱具有明显的效果,位移滞回性能、加固柱的抗震性能和延性得到明显改善。
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.
