    Abstract
    A brief review of the basic points of a suction-based heat, moisture transfer and skeleton deformation equations for an unsaturated medium is presented. The main issues such as: two temperature-dependent state surfaces of void ratio and degree of saturation which are used to present the coupling effects of temperature, moisture content and deformation of skeleton; the new thermoelastoplastic constitutive law, etc. are briefly mentioned. The Bubnov–Galerkin integral form of field equations has been developed as the basis of spatial and temporal discretized matrix form. The single-step integration in time is described. The numerical solution algorithm of the finite element package, θ-STOCK, is presented. Some application cases are presented and discussed to show the strong ability of presented model and the prepared numerical package.
