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.

The randomness of cumulative fatigue damage process was caused inner dispersion, the uniformity microstructure of materials, and external dispersion, the randomness of the load.
Then dispersion of instantaneous cumulative damage statistical is not considered caused by dispersion of materials and loads[5-6].
Inner dispersion is an inherent specialty of materials got through experiment, while external dispersion is mainly reflected by randomness of the load, containing random arrangement and the random distribution of load size.
