The behaviour of high-strength reinforced concrete columns under low eccentric loading
In this study, the change of the behaviour of high-strength reinforced concrete (HSRC) columns under axial and eccentric load based on the ratios of transversal and longitudinal reinforcements was investigated. To do this, 2100 mm height and 200 mm × 300 mm cross-sectional sizes reinforced concrete columns which have different transversal and longitudinal reinforcement ratios were produced with high-strength concrete. On these produced columns, two different eccentricity (e = 25 mm and e = 50 mm) and axial (e = 0) loadings were done. The experimental and theoretical moment–curvature (M–K) relations were determined and compared with each other. Test results showed that in the HSRC columns, the ratio of longitudinal reinforcement did not changed the fracture type which was brittle, but when the ratio of transversal reinforcement increased, the type of fracture was changed. The M–K relation obtained from the experiments and the M–K relation calculated theoretically were in harmony. This showed that the material model which was used to determine theoretical M–K relation was suitable for HSRC.
