stress-strain curveThis paper presents a stress–strain curve that describes the axial behavior of concrete in circular columns with lateral reinforcement. As opposed to most studies on this subject, which used semiempirical methods, the proposed stress–strain relations are based on a theoretical ...
compressive stress-strain curveThe strength and deformation capacity of concrete will deteriorate due to theerrosive materials in the environment,such as salts,acid,and microorganism. Uniaxialcompression tests were made to develop the stress-strain model for the corroding concrete.According to the ...
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...

The purpose of this investigation is to propose the analystical expression of stress-strain curve for concrete under cyclic loadings through a stochstic process theory it is necessary to make clear five item, which are envelope curve, elastic modulus, residual strain reloading curve and unloading cu...
The stress-strain curves of normal weight concretes of strenghts up to 11,000 psi and lightweight concrete of strengths up to 8000 psi are reported. An analytic expression for the stress-strain curve of concrete is developed to reflect experimental results. The analytic expression has four ...
Park, 3 Fellow, ASCE ABSTRACT: A stress‑strain model is developed for concrete subjected to uniaxial compressive loading and confined by transverse reinforcement. The concrete section may contain any general type of confining steel: either spiral or circular hoops; or rectangular hoops with or ...
