Abstract

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 the value of a single parameter - maximum temperature during fire. Numerical experiments demonstrating that fire behaviour of concrete can be described with a single function are presented, and directions for further study are proposed.
