Axial Compression Ratio on Seismic Performance of CFPR Steel Tube Composite Columns Filled with Steel Reinforced Concrete
To study the mechanical properties of CFPR steel tube composite columns filled with steel reinforced concrete under different axis compression ratio by adopting 3 specimens of theirs quasistatic tests are carried out. The failure mechanism and test results are analyzed with member of the load-displacement hysteretic curves, skeleton curves. The results show that the axial compression ratio decreases conducive to the improvement of the bearing capacity of specimens. Axial compression ratio has a great influence on the skeleton curve and ductility. Axial compression ratio is higher, the descent stage of the skeleton curve is steeper, the ductility is better. With the increase of the axial compression ratio, the ductility coefficient and energy dissipation capacity is lower.
