【 摘 要 】

A model of concrete deformation under the high temperature heating in a loaded state is proposed. It reflects the physical nature of deformation has a rather compact form and requires a minimum number of normalized parameters. In order to describe the curve of concrete deformation and temperature parameters change exponential relationships were assumed and calibration of their coefficients was performed.
