Abstract

The quality of computational modelling of thermomechanical behaviour of building structures and their components is conditioned by the reliable design and evaluation of all constitutive relations, included in the model. The identification of corresponding material characteristics is usually much more complicated then the standard analysis of response of a structure to various type of loads, thus very special measurement configurations are needed. The paper demonstrates an advanced identification approach on a model problem of evaluation of heat conductivity and heat capacity in the linearized Fourier equation with (a priori unknown) boundary heat transfer, motivated from real direct and inexpensive non-stationary measurements of thermal technical properties of building materials, applicable both in a laboratory and in situ.
