This study investigates the dependence of the mechanical behavior of concrete, such as strength, stiffness, and deformation capacity on the damage caused by freezing and thawing cycles (FTC). A stress-strain model for concrete damaged by freezing and thawing prior to the application of mechanical ...
A complete stress-strain curve model for concrete confined by rectilinear reinforcement was proposed. In this model, the confinement effect of rectilinear steel, including common hoops and square steel tube, was evaluated by using effective lateral pressure factor. Major variables influential in the con...

An experimental investigation into the behavior of plain concrete under cyclic loading is described. Stress-strain curves obtained for concrete cylinders under such loading are presented, and analytical stress-strain relations for cyclic loading are derived. Assuming the property of uniqueness of stress-...

In this paper, a stress–strain model for concrete confined by fiber reinforced polymer (FRP) composites is developed. The model is based on the results of a comprehensive experimental program including large-scale circular, square and rectangular short columns confined by carbon/epoxy and E-glass...
Therefore establishing axial stress, axial strain, and lateral strain relationships is a timely concern. Based on shear failure of concrete, a simple strain-based model is proposed in this paper. It is developed using prevailing test results for HSC with active confinement. 展开 ...
