The Impact of the Coefficient of Absorption of Solar Radiation on the State of Stress in Heterogeneous Masonry

摘要

The masonry is heterogeneous material created from stones and mortar. The material characteristics of masonry components may differ in many aspects. The intention of this paper is the description of the thermal stresses which are generated by different values of coefficient of solar radiation absorption. The results were obtained by means of the 3-D finite element model of masonry. The difference of absorption coefficient between stone and mortar may cause increase of pressure thermal stress.
