Building materials such as concrete, bricks or mortar do have a very slow response to temperature changes due to their low heat conductivity.
Actually, all materials at a temperature above absolute zero continuously emit energy, which is transmitted in space in the form of electromagnetic waves [5].
IR thermography can sense the radiation from the material surface, and produce a visual image from this thermal signal.
A commercially available finite element software (MARC, 2000) is used to compute the temperature field in the electro-thermal material.

Introduction In this paper according to the material properties of structural steel and concrete under high temperature, the bonding strength changing laws with different temperature and its formula of the profiled steel sheet-concrete are deduced, and obtained the bonding stress-slip relationship, so as to established a nonlinear finite element method of analyzing the steel concrete composite slab fire properties.
Temperature distribution is unrelated to stress levels , whereby the temperature analysis will not consider the influence which component deformation, cracking, stress and strain level and other factors impact on the thermal parameters of materials and components thermal conduction. 4.
Material stress-strain line is a nonlinear elastic relationship.
