Unique function for describing stress and strain behaviour of fire-affected concret

[摘要] A unique analytic function for the approximation of EC2 curves describing dependence of stress and strain of concrete at fire-generated temperatures is presented n the paper. The proposed function enables generation of a family of curves differing only in
