This paper introduces a new way for section description, which is based on the section intrinsic times and could be used for either homogeneous members or composite members. According to the irreversible thermodynamics, the establishment of the energy conservation equation in the partial length of member and the section constitutive equation with integral style is introduced in detail. For the sake of simplicity, a practice model with the synthetic section-time is proposed and the incremental equations convenient to numerical methods of member nonlinear analysis are introduced. The mathematical equations of the model are uniform for various loading situations, and the computer programming work at the section level could be greatly simplified when it is put into use in member nonlinear analysis. The method for determining the model parameters is discussed and some improvement suggestions are proposed for further researches at the end of the paper.
