Seismic Performance of Full-Scale Reinforced Concrete Columns

The results of the simulated seismic tests conducted on five full-scale reinforced concrete columns are presented in this paper. Experimental results show that the shear span-depth ratio at high axial load levels can significantly reduce the member performance of columns due to the P-Δ effect. In addition, the axial load applied on a column plays an important role in determining the plastic hinge length. As the plastic hinge length depends on the axial load, the relationship between the sectional and member behaviors is affected by the axial load. [PUBLICATION ABSTRACT]
