Modelo de comportamiento estructural de muros entramados de madera en el siglo XIX en España

Abstract

In this article the structural behavior of a timber- framed wall is analysed. The wall is composed by a timber grid of vertical parts (posts) and horizontal elements (beams), whose panels are normally filled with plaster rubble. This system was widely used as a load-bearing wall system in the Spanish residential buildings between the 17th and 19th centuries. The research concludes that the loads are transmitted mainly through the infills by vertical compression, and that the deformation of the beams by bending is negligible, except in those cases in which there is no infill at the bottom. Also, using numerical simulation by finite elements, a formula determining the percentage of total loads absorbed by posts and infills is obtained depending on their rigidity to compression, so as to quantify the stress state of them. This is a fundamental aspect in the design and dimensioning of reinforcements in structural rehabilitation.
