The stone object of this research study comes from the Church of Santiago de Jerez de la Frontera. It is a material widely used in the construction of historical heritage buildings. It is a sandstone that belongs to the Cerro de San Cristóbal quarry which, for different reasons ‐ economic, logistical and workability ‐ has been widely used...

The use of Operational Modal Analysis is establishing as an acceptable tool to estimate the dynamic properties of heritage buildings as a non‐destructive technique. Through its application, mechanical properties of structural elements, as stiffness or mass, can be obtained with great accuracy. The information obtained can...

San Cristóbal's is a porous sandstone that is present in masonry structures of numerous historical buildings located in the southwest of Spain (15th–18th centuries). In order to guarantee conservation and structural integrity, most of these structures have been assessed during the last two decades after they presented severe damages in...

This work presents a relationship between static and dynamic elastic moduli for San Cristóbal's stone, which was used to build some of the most representative historical constructions in Andalusia (Spain) during 15th-18th centuries, including religious, military and civil buildings. Numerical models are able to provide useful information in...

La alteración de la Piedra arenisca es una inquietud para los técnicos y restauradores del patrimonio histórico, ya que es la piedra base de muchos edificios de nuestro patrimonio histórico. En este trabajo nos vamos a centrar en la piedra extraída en el Cerro de San Cristóbal, situada en el Puerto de Santa María (Cádiz). Una de las...

The purpose of this paper is to bring the numerical models' structural behavior closer to the real behavior of the Church of Santa Ana in Seville, in Triana, through the development of high-definition geometric models that incorporate the non-linear materials' behavior. This church is presented as a unique case study due to the geometric...

This article presents an innovative metamodeling approach for predicting the effective elastic properties of cement grouts containing carbon nanotubes (CNTs), for the purpose of structural rehabilitation. The study addresses the homogenization of nano- and micro- scales through a Representative Volume Element (RVE). The numerical model consists...
