“…The researches range from investigation surveys and experimental works (Binda et al 2005;Ivorra et al 2009;Anzani et al 2010;Russo et al 2010;Bartoli et al 2013) to dynamic identification studies (Ivorra and Pallarés 2006;Gentile and Saisi 2007;Ramos et al 2010;Pieraccini et al 2014). With respect to the experimental activities, in some cases, starting from a field survey of the actual configuration including (if present) the cracking pattern, nondestructive tests (e.g., dynamic tests, sonic pulse velocity tests, thermography, etc.)…”

This paper focuses on the seismic risk assessment of historic masonry towers according to the Italian "Guidelines for the Assessment and Mitigation of the Seismic Risk of the Cultural Heritage." The latter identifies a methodology of analysis based on three different levels of evaluation, according to increasing requirements on the structural knowledge: LV1 (analysis at territorial level), LV2 (local analysis), and LV3 (global analysis). Regardless of the methodology of analysis, the more advanced the achieved level of knowledge, the higher the reliability of these approaches becomes. In this field, a fundamental task is the estimation of the uncertain parameters (both material properties and boundary conditions) affecting the structural behavior. The effect of these uncertainties on the global structural response is herein approached through the discussion of an illustrative case study of some of the historic masonry towers in the city center of San Gimignano (Siena, Italy). The seismic risk of these towers was analyzed in the framework of Seismic Risk of Monumental Buildings (RiSEM is the Italian acronym), a research project granted by the Tuscany Regional Administration, and this paper summarizes the results obtained for two of the preceding three levels, which highlights a few issues concerning the seismic risk of historic masonry towers. Useful conclusions are drawn in order to quantify, when performing an LV3 approach through nonlinear models, the effects of the uncertainties on the seismic risk evaluation of such structural typology. The paper, in particular, confirms once more how strongly the effect of confinement reflected on tower seismic performances and stresses that specific attention should be paid to the definition of the effective portion of the structure to be considered as confined (with respect to adjacent buildings).

“…Regarding CH assets, GPR is useful for investigating deformation of hollow piers due to mechanical stress [3], and for studying the signal reflected by objects inside structures such as bridges or viaducts [4][5][6][7]. Moreover, it allows us to analyze the state of conservation of ancient buildings from historical, archaeological, and structural points of view [8][9][10][11][12]. These examples represent only a small portion of the wide existing literature.…”

Structural Assessment via Ground Penetrating Radar at the Consoli Palace of Gubbio (Italy)

Ground Penetrating Radar (GPR) is a flexible and cost-effective tool for performing structural integrity assessment and quick damage evaluation of manmade structures, including cultural heritage (CH) assets. In this context, this paper deals with the usefulness of GPR surveys enhanced by the use of a Microwave Tomographic data processing approach as a methodology for the diagnosis and monitoring of CH exposed to climate events and natural hazards. Specifically, the paper reports on the results of a measurement campaign carried out at the Loggia of the Consoli Palace of Gubbio (Italy). These results allowed us to increase our knowledge of the architecture of the surveyed zones and their structural hazards.

Existing slender masonry structures, such as Pagoda temples, towers, minarets and chimneys, exist all over the world and constitute a relevant part of the architectural and cultural heritage of humanity. Their protection against earthquakes is a topic of great concern among the earthquake engineering research community. This concern mainly arises from the strong damage or complete loss suffered by these types of structures when subjected to earthquake and also from the need and interest to preserve them. This chapter firstly presents a methodology for assessing the seismic vulnerability of slender masonry structures based on vulnerability index evaluation method. Secondly, presents the correlation between vulnerability index and Macroseismic method to estimate the physical damage in relationship with seismic intensity. Finally, presents implementation of the methodology to construct vulnerability curves, fragility curves and estimate losses.
