| description | Self Compacting Concrete offers many advantages over conventional concrete. It is mainly used when a great fluidity is required (For example sections with high percentage of reinforcement). Self Compacting Concrete has excellent applicability for elements with complicated shapes and congested reinforcement. An experimental study was made on cylinders and specimens with square sections confined by lateral reinforcement to investigate the effectiveness of transverse steel on M 40 grade concrete under monotonically increasing axial compression. The behavior of SCC cylinders confined by circular hoops and square prisms by rectilinear hoops with different volumetric ratios and spacing were compared under axial compression. The effects of the test variables such as volumetric ratio, spacing and shape of cross section on the behavior of SCC specimens are presented and discussed. The results revealed that the more the volume of confinement steel, more the increase in peak stress and deformability. Test results of this study were compared with existing confinement models of Saaticioglu-Razvi, Mendis, Legeron and Paultre, and Mander. The study indicates Mander's model is nearer to the test results. |
