“…The results are similar to those obtained in other comparable studies [8,11,13,16], except in the case of bricks of G3, in which the average strength is between 45.1 and 64.4 N/mm 2 . Unusual strengths, higher than 50 MPa, were also reported by Pauri et al [40].…”

“…The mechanical analysis of bricks is common in many of them, including the works of Fernandes and Lourenço [6], Singha, et al [7], Matysek et al [8], Balasubramanian et al [9], Azeez et al [10], Pérez-Gálvez et al [11], Brozovsky et al [12] and Bajare et al [13]. Because of the difficulty of extracting samples, estimates of the bearing capacity of brick walls based on empirical formulas and analytical models that use the bricks and mortar strength are very useful.…”

Abstract:Interventions in historic brick buildings require an exhaustive analysis of the current characteristics of bricks in order to establish the role performed by these elements in the buildings. This study presents the results of an experimental analysis of the compressive strength of brick specimens extracted from different buildings built in the 19th and 20th centuries in the province of Zamora (Spain). The study analyses specimens with very different characteristics to compare results from different masonry units and manufacturing processes. Specimens are classified into four groups according to their macroscopic and microscopic analyses. Compressive strength results are correlated to the above classification and to the results of density, absorption and open porosity of the samples. The compressive strength results present high variation between clay bricks (9.2-64.4 N/mm 2 ) and between samples extracted from the same brick due to the heterogeneity of the material. Correlations between compressive strength and open porosity, absorption and dry density values are observed, with less dispersion in the case of high sintering level, up to 1000 • C. Finally, the compliance with the current Spanish Technical Building Code with respect to their compressive strength is checked.

On-Site Risk Assessment Methodology of Historic Timber Structures: The Case Study of Santa Cruz Church

et al. 2022

The conservation and repair of historic structures require significant resources. Therefore, it is important to conduct a complete assessment of the object. Specifically, historical timber frame structures are very common in the Spanish and Andalusian geographic area. This research proposes and develops a simplified approach to facilitate decision making when faced with this complex work. By the application of long-established non-destructive tests, such as organoleptic and measuring inspection, resistography, and electric moisture content test, combined with visual classification parameters, these data were used as boundary conditions into a simplified structural calculation method. This process, which is simpler than other calculation systems, allows compiling important information about the safety level of the structure and its critical points. Finally, it allows for a better approach to repair work while rationalizing resources. This method was applied to a historical structure, during an 18th century church repair project. The assessment methodology provided important information about the conservation state of the timber frame and its structural suitability.

“…A pesar de que se trata de un análisis del que no se pretende obtener una historia de evolución de grietas, sí pueden extraerse datos orientativos que ayuden a entender el comportamiento general del edificio (10). El análi-sis se realiza teniendo en cuenta cargas gravitatorias exclusivamente y considerando distintas fases del proceso constructivo.…”

RESUMENEste artículo pretende describir la respuesta estructural de la Torre del Homenaje, una de las torres del complejo de la Alhambra (Granada), y por otro lado revisar las distintas técnicas utilizadas en el análisis estructural de edificios históricos aplicándolas a dicho objeto para valorar el alcance de cada una de ellas.La torre se analiza mediante tres procedimientos con diferentes niveles de complejidad. En primer lugar, se utiliza el mé-todo de líneas de empuje para valorar los diferentes coeficientes de seguridad desde un punto de vista de la estabilidad. En segundo lugar, se lleva a cabo un análisis elástico y lineal aplicando el método de los elementos finitos para identificar posibles concentraciones de tensiones de tracción.Por último, se ha realizado un análisis estático no lineal tipo pushover sobre cinco modelos numéricos diferentes para valorar la respuesta estructural ante acciones horizontales de los muros perimetrales y de los pórticos interiores.Palabras clave: Fábrica de ladrillo; análisis estructural; Alhambra; pushover. ABSTRACT This paper aim, on one hand, to describe the structural response of "Homenaje Tower", one of the towers of the Historical Complex of the Alhambra, in Granada (Spain) and, on the other hand, to look over the different techniques used in the structural analysis of historical buildings, applying them to the tower to assess the scope of each of them.The tower is analyzed from three methods that count on different levels of complexity. First, an analysis using graphical method for limit analysis is carried out to assess the different safety coefficients from a stability point of view. Secondly, a finite element linear elastic analysis is applied in order to identify possible stress concentration zones, in particular zones with tensile stresses.Finally, a nonlinear static pushover analysis has been carried out over five different numerical models to assess the structural response to horizontal loads of perimeter walls and interior porticos.
