En este artículo se presenta una metodología que permite obtener de forma automática la geometría de muros de mampostería para proceder al cálculo estructural mediante elementos finitos considerando por separado las unidades estructurales (ladrillo o piedra) y el mortero. Esta geometría se obtiene mediante un proceso de detección de bordes en fotografías digitales de los muros analizados. A modo de ejemplo se presentan dos aplicaciones de este metodología. Una de ellas es el análisis de unmuro de mampostería regular de obra. La otra aplicación es el análisis de un muro de mampostería de piedra irregular. El cálculo computacional en ambos casos se ha basado en un modelo sencillo propuesto que permite simular el deterioro del muro de mampostería debido a la fisuración por tracción de las juntas. Suumary This paper presents a proposed methodology developed to obtain the geometry of masonry walls. The methodology is based on the automatic recognition of boundaries. The geometry is used to proceed to the numerical simulation of damages based on a simple model, which allows determinate the cracking process due the tensile stresses in joints. Masonry units are considered as lineal and elastic elements, and the non-elastic processes are considered to exist only in the joints. Two examples are included showing two different walls: a regular mansonry wall built with bricks, and an irregular masonry wall with limestone stones as masonry units.

Abstract

This paper presents a proposed methodology developed to obtain the geometry of masonry walls. The methodology is based on the automatic recognition of boundaries. The geometry is used to proceed to the numerical simulation of damages based on a simple model, which allows determinate the cracking process due the tensile stresses in joints. Masonry units are considered as lineal and elastic elements, and the non-elastic processes are considered to exist only in the joints. Two examples are included showing two different walls: a regular mansonry wall built with bricks, and an irregular masonry wall with limestone stones as masonry units.
