Plastic strain and stress deterioration of FRP-confined concrete prisms under axial cyclic compression
This paper presents the investigation and modeling of Plastic strain and stress deterioration of FRP-confined concrete prisms under axial cyclic compression. Also the effect of the cross-section shape of specimens on these parameters is investigated. For this purpose, the experimental results of cyclic stress-strain behavior of circular, square and rectangular concrete prisms confined by FRP-composites are presented and examined. Besides, the effect of repeated complete cycles on the plastic strain and stress deterioration is studied. The results show that the relation between plastic strain and first unloading strain is linear and depends only on the two parameters of concrete strength and the shape of cross-section, but the stress deterioration depends only on the first unloading strain. The predictive formulations for plastic strain and stress deterioration are presented and compared with the experimental results.
