Hysteretic Behavior of Reinforced High-Strength Concrete Sections |
Abstract |
The objective of this research is to evaluate the hysteretic behavior of reinforced high-strength concrete section subjected to repeated reversal loadings. An analytic method is presented for the derivation of the moment-curvature relations for the section subjected to repeated reversal loadings in the inelastic range. The method utilizes stress-strain models for high-strength concrete and reinforcing steel subjected to cyclic loadings. Computer programs were developed to compute the bending moment and the curvature for cyclically loaded reinforced high-strength concrete sections with or without constant axial compression. The analytic approach is used to estimate the effects of factors, such as the strength of concrete, the tension and compression reinforcement, the axial load, yield strength of steel, and the confinement of stirrup affecting the behavior of reinforced high-strength concrete section under load reversals. |
