Distribución de tensiones en fachadas de azulejos sujetas a dilataciones térmicas

Abstract

Tiles have been widely used in building facades due to important qualities such as little maintenance needed and high performance under aggressive environmental conditions, but tiles also present some limitations. One among them is that tile glaze brakes after collocation, usually due to the high temperature range facades undergo. The present work studies the stresses that take place in a tile facade when is submitted to high temperature variation. Special emphasis in the analysis is taken on the outer system elements. The problem is represented by means of a numerical solution using the Finite Element Analysis. Two different geometrical shapes commonly found have been modeled, a square tile with straight border and square tiles with a beveled edge.
