Influence of confinement on high strength concrete behavior
Abstract An experimental program has been made in order to study the confined concrete behavior when its strength changes from traditional values to high strength values and with confinement levels ranging from 0% to values higher than 4%. The specimen shape and size have also been included as variables. With the data experimentally achieved, the parameters that define the stress-strain curve for concrete were adjusted using a statistical methodology that gives us suitable approximation levels. A stress-strain curve model is proposed, which lets us know precisely the confined concrete behavior up to high strain levels and analyze the material ductility. The achieved improvement, thanks to the confinement, was quantified regarding the parameters that define the concrete behavior, particularly the maximum strength, the strain at the peak and the ductility.
