Abstract
Sistemas constructivos medievales a menudo involucrados la construcción de múltiples capas
paredes formadas por dos caras de sillería o mampostería con un relleno central que consiste en
escombros ligada con mortero, generalmente cal-basado. Se trata de una construcción simple y eficiente
sistema que se siguió utilizando en los siglos posteriores.
Sin embargo, el modelado estructural de este tipo de pared no es fácil de lograr. Los dos pared
caras no están vinculados rígidamente y, por otro lado, las bóvedas son normalmente compatibles sólo en el
la cara interna, lo que resulta en la eficiencia reducida de la unidad de pared. Modelos comunes de elementos finitos
no son capaces de resolver muchos de los problemas que surgen cuando se aplican a una monumental
construcción.
En este trabajo se aborda el problema y propone varias posibilidades de solución con diferentes
tipos de elementos .. También proporciona dos ejemplos de monumentos góticos en Galicia (España) en el que
comportamiento estructural se ha estudiado el uso de algunos de estos modelos de cálculo: las iglesias de Guimaraens y Cambados.
[Abstract]Medieval construction systems usually involved the construction of multi-layer walls formed by two faces of ashlar work or masonry with a central infilling consisting of rubble bound with mortar, generally lime-based. It is a simple and efficient construction system which continued to be used in subsequent centuries. Nevertheless, structural modelling of this type of wall is not easy to achieve. The two wall faces are not rigidly bound and on the other hand, vaults are normally supported only on the intemal face, resulting in reduced efficiency of the wall unit. Common models of finite elements are unable to solve many of the problems that arise when they are applied to a monumental construction. This paper tackles the problem and puts forward various possibilities of solution with different element types.. It also provides two examples of Gothic monuments in Galicia (Spain) in which structural behaviour was studied using some of these calculation models: the churches of Guimarei and Cambados.
