“…Macromodeling, in contrast, assumes homogenous constitutive behavior for the masonry and mortar assembly and, therefore, is commonly applied to model large-scale structures. The suitability of the homogenized material property assumption has been confirmed in numerous studies (Creazza et al 2002). Therefore, the discussion in this section will focus on macromodeling.…”

“…A very similar study with the same purpose was repeated a year later on a masonry, ribbed cross-vault scaled model and a masonry, barrel-vault scaled model by Creazza et al (2002). This study focused on the locations and magnitudes of maximum strain and deformations as well as on the characteristics of the collapse mechanism under slowly increasing static load.…”

About the Cover:The figures on the cover illustrate three aspects of the validation of a computational model developed to predict the vibration response of historic masonry monuments. Top right: The National Cathedral, Washington, DC, where vibration response of vaults is experimentally measured to assess the effect of structural damage. The measurements provide acceleration time series used to verify and validate predictions of the numerical simulation. Top left: The computational finite element model is shown to illustrate the mesh discretization of a vault. The model is analyzed to simulate the vibration response. Colors represent different material properties whose uncertainties are propagated through the calculation. Bottom: The measurement of a vibration mode shape of the structure (solid line) is compared to the prediction of the finite element model (dashed line). Crosses illustrate the uncertainty of predictions due to variability of the boundary conditions and material properties. Statistical tests are implemented to quantify the accuracy of the finite element model, given measurement variability and prediction uncertainty. Tables Table 3- Calibration Under Uncertainty for Finite List of Figures List of ABSTRACTHistorical unreinforced masonry buildings often include features such as load bearing unreinforced masonry vaults and their supporting framework of piers, fill, buttresses, and walls. The masonry vaults of such buildings are among the most vulnerable structural components and certainly among the most challenging to analyze. The versatility of finite element (FE) analyses in incorporating various constitutive laws, as well as practically all geometric configurations, has resulted in the widespread use of the FE method for the analysis of complex unreinforced masonry structures over the last three decades. However, an FE model is only as accurate as its input parameters, and there are two fundamental challenges while defining FE model input parameters: (1) material properties and (2) support conditions. The difficulties in defining these two aspects of the FE model arise from the lack of knowledge in the common engineering understanding of masonry behavior. As a result, engineers are unable to define these FE model input parameters with certainty, and, inevitably, uncertainties are introduced to the FE model.As the complexity of the building increases, as is the case for historical unreinforced masonry buildings, the errors and uncertainties in the analysis also increase. In the presence of high and numerous uncertainties originating from multiple sources, deterministic approaches in which parameters are defined as constant values assumed to be known with certainty cannot be implemented reliably. Probabilistic methods, however, provide a rigorous and rational means in treating the uncertainty present in the FE analysis of historical unreinforced masonry buildings. The way in which uncertainty in historical unreinforced masonry construction is treated is one of the novel and main contributions...

Abstract.A study of the mechanical behavior of brick masonry vaults with cut aperture is presented. The vault in New Holland complex in St. Petersburg was assumed as an illustrative example. This vault was tested and simulated in order to evaluate its stress-strain state.Comparison of the results of numerical analysis and experimental test data has been performed. The optimal way to perform an aperture was defined: aperture should be cutting parallel to the lines of action of the principal stresses minimizing direction transversal to these lines. As a further development of the research, the investigation of the various types of aperture in vaults has been recommended to perform using different simulating models and methods.

“…En ese contexto, Peña-Mondragón (2010) menciona que además de esos factores propios de la estructura física, se debe tener especial cuidado con otros factores numéricos, como lo son la descripción geométrica, el diseño estructural, la buena identificación de los materiales utilizados en la construcción, así como de las propiedades mecánicas y calidad de dichos materiales. Por otro lado, de acuerdo con Creazza et al (2002) para el análisis de este tipo de edificios de mampostería como el Museo de la Insurgencia, existen dos aproximaciones generales: el micromodelado que está definido por la utilización de elementos continuos de las piezas y las juntas, y macromodelado que representa a la mampostería como un solo medio homogéneo (López et al, 1998). En cuanto al grado de complejidad de un modelo numérico que incluye aproximaciones lineales y no lineales, Lourenço (2001) recomienda realizar modelos simples lineales para análisis preliminares y tener un conocimiento del comportamiento global de la estructura.…”

RESUMENEl Museo de la Insurgencia, declarado edificio histórico y patrimonial y localizado en Pabellón de Hidalgo, estado de Aguascalientes, México central, está siendo severamente dañado por una falla superficial activa. Para este trabajo se implementó una metodología sencilla para monitorear y cuantificar los desplazamientos derivados de la falla a partir de los cuales se realizó un análisis lineal de esfuerzos mediante simulaciones numéricas para evaluar daños estructurales, identificar puntos críticos y realizar una predicción aproximada de situación estructural crítica en un futuro próximo. La metodología incluye una revisión de la última adecuación estructural del edificio diseñada para que éste conviviera con la falla que lo afecta. Utilizando fisurómetros colocados estratégicamente en los elementos constructivos del museo a lo largo de la línea de falla se logró la evaluación cuantitativa de los desplazamientos inducidos por la falla. El monitoreo se realizó por un lapso de 202 días obteniéndose desplazamientos verticales y horizontales máximos de 6 mm y 10 mm, respectivamente. Los resultados de las simulaciones numéricas permitieron determinar que, bajo las condiciones dinámicas actuales del efecto de la falla, el edificio está siendo críticamente dañado en las bases de las columnas más cercanas a la falla, de tal modo que en un periodo de mediano plazo los esfuerzos inducidos por la falla sobrepasarán la resistencia del edificio en algunos puntos.Palabras clave: Falla geológica; Museo de la Insurgencia; valle de Aguascalientes; análisis numérico MONITORING DAMAGES AND NUMERICAL ANALYSIS IN A HISTORIC BUILDING AFFECTED BY AN ACTIVE SURFACE FAULT IN THE VALLEY OF AGUASCALIENTES ABSTRACTThe Museum of the Insurgence, inherited historic building located in the community of Pabellon de Hidalgo, Aguascalientes state, central Mexico, is been severely damaged by an active surface fault.
