Abstract:
A moment-curvature analysis based on hysteresis models of materials was conducted to reproduce the response of high-strength reinforced concrete column specimens subjected to varying triaxial forces. The relationships between the ductility and axial deformation of such columns were examined by a parametric analysis using the same models. The effects of varying axial load on the ductility and axial deformation characteristics of reinforced concrete columns are described, based on both the experimental and analytical results in this paper. The required items in a confinement design for reinforced concrete columns under varying triaxial forces are also examined.
