En este trabajo se presenta la caracterización de los morteros de diferentes elementos constructivos en el Templo Romano de Diana con vista a su conservación. Las muestras de mortero que fueron recogidas de diferentes partes del Templo se caracterizaron por microscopía óptica polarizada (POM), difracción de rayos X (DRX), análisis térmico (ATG-DSC) y fluorescencia de rayos X (FRX). Los resultados de la microscopía óptica revelaron que los morteros fueron realizados con un aglomerante de cal, y con agregados de cuarzo, feldespato y biotita junto con fragmentos de rocas graníticos y metamórficos. Los análisis DRX apoyan las observaciones microscópicas y añaden la información de presencias de actinolita en los agregados que indican el mismo origen de las rocas graníticas y metamórficas del entorno geológico de Mérida (España) y muestra la ausencia de biotita en el mortero de suelo y poco cuarzo en el mortero de mampostería de criptoporticus. Según los resultados proporcionados con ATG-DSC y FRX los morteros utilizados para la construción del canal frente al Templo, la fundación de sillería de granito y la pared interna de criptoporticus tienen alto carácter hidráulico. Para la conservación futura del monumento es necesario tener presente estas características para el diseño de los morteros de restauración a utilizar.

Seismic and Restoration Assessment of Monumental Masonry Structures

Masonry structures are complex systems that require detailed knowledge and information regarding their response under seismic excitations. Appropriate modelling of a masonry structure is a prerequisite for a reliable earthquake-resistant design and/or assessment. However, modelling a real structure with a robust quantitative (mathematical) representation is a very difficult, complex and computationally-demanding task. The paper herein presents a new stochastic computational framework for earthquake-resistant design of masonry structural systems. The proposed framework is based on the probabilistic behavior of crucial parameters, such as material strength and seismic characteristics, and utilizes fragility analysis based on different failure criteria for the masonry material. The application of the proposed methodology is illustrated in the case of a historical and monumental masonry structure, namely the assessment of the seismic vulnerability of the Kaisariani Monastery, a byzantine church that was built in Athens, Greece, at the end of the 11th to the beginning of the 12th century. Useful conclusions are drawn regarding the effectiveness of the intervention techniques used for the reduction of the vulnerability of the case-study structure, by means of comparison of the results obtained.

“…The statistical evaluation of the results has led to the development of fragility curves that correlate the estimated damage to the seismic intensity based on a given type of probability. Indicative fragility curves for the Kaisariani monastery are shown in Figure 12b referring to the failure criterion depicted in Figure 12a [18,23]. The main purpose of the analysis of a monument or a historic building is to assess its seismic risk in order to propose specific intervention measures for an effective seismic upgrade and protection of such structures.…”

“…Beyond identifying these components, namely the structure and the mechanical properties of the materials, the scientific community interest focuses on the modeling approach of historic mortars, since application of inappropriate mortars for the preservation of monuments in the past resulted in devastating effects, i.e., cracks, failure of the original materials, surface staining or spalling. A thorough and organized survey of the two monuments has been conducted including the implementation of various non-destructive techniques (NDTs) [17][18][19]. In the case of Kaisariani monastery, after a thorough in-situ macroscopic investigation, a variety of NDTs where ap-…”
