“…This volume is prefabricated and anchored by bolts and tie rods to the reinforced concrete base structure. If, on the other hand, it is a masonry structure, the base structure must be reinforced at the attachment points (Calderoni et al, 2016;Guadagnuolo et al, 2020). In all cases, the anchors have to be made of local verifications.…”

The pandemic Covid-19 has distorted the way of living and enjoying the spaces. Unfortunately, cities are often saturated and many of the public buildings fail to meet the new needs. The need to expand the spaces is a problem and an opportunity: intervening on the existing patrimony, however, requires a multidisciplinary commitment. The interventions on the built heritage have several problems, on the one hand technological, aimed at improving the energy impact of the new building, and on the other properly structural, because the existing heritage was not always built with seismic requirements. This article presents some possible solutions for intervention on the existing patrimony for the implementation of the spaces through volumetric addition, "parasitic architecture", and how the use of wood and its derivatives can allow it.

“…Among the lime mortars the pozzolanic ones have a key role in all the Roman architecture and have been used in large part of the world following traditional compositions, since the Vitruvius treatise (Vitruvius, 1960) and until the XIX century treatises (Rondelet, 1827;Claudel et al, 1863). The assessment of ancient structures, often located in earthquake vulnerable areas, is a complex process involving historical analyses, structural models, vulnerability evaluations and should be carried on with great care Guadagnuolo and Faella, 2020c). The simple knowledge of the actual geometry of the structure cannot be in fact sufficient if not appropriately connected to a rational coordination of the information about the whole past of the monument (Frunzio et al, 2019;Bergamasco et al, 2017 and together with the material properties (Monaco et al, 2014;Guadagnuolo et al, 2020b).…”

Large part of world Cultural Heritage is located in earthquake vulnerable areas and built with materials there available. The seismic events occurred in the course of the lives of these buildings have evidenced the strong dependence of the damages on the mechanical properties of the building materials. Recent seismic codes foresee for these buildings performance-based demands, so that the intervention materials' properties should be correctly calibrated. This is especially true for traditional structural mortars, particularly the lime-based ones. Mechanical tests on samples of structural mortars taken from existing buildings are rare, so that laboratory reproduction of ancient mortars based on traditional composition allow to detect reference values for restoration materials fulfilling code requirements. This paper presents the results of a wide set of mechanical tests on a pozzolanic lime mortar, largely diffused in Southern Italy mortars. Three types of mortars and three different curing ages were tested and the results were analyzed, to assess the reliable use of traditional mortars in the restoration field.

“…In particular, experience shows that a broader study of the monument, the history and architecture of the building, its material consistence and actual state are indispensable prerequisites for the successive analyses, in order to account for all initial and consecutive construction phases, previous interventions or additions (Bosiljkov et al, 2010;Asteris, et al, 2017). Furthermore, the results of the experimental investigations regarding geometrical data, the in situ evaluation of the materials mechanical characteristics (Monaco et al, 2021a and2021b;Guadagnuolo et al, 2020a), the properties of the structural elements like masonry walls, arches, vaults and floors, the complex response of the construction to different possible actions, as well as the results of eventual previous monitoring can be crucial for reliable designing interventions on ancient structures (Monaco et al, 2014;Gesualdo and Monaco, 2015;Guadagnuolo et al, 2020bGuadagnuolo et al, , 2020c. In the case of San Gimignano towers "...the construction is surprising, the method is based on very thick stone masonries and extraordinary mortars, with just a few later exceptions where bricks were used" (Giorgi and Matracchi, 2017).…”

Masonry buildings are the main part of the Architectural heritage in the World. The need of preservation for the historical memory, together with the exigence of fruition and use, has evidenced the need of appropriate analysis tools. In general, the stresses in masonry structures are usually considerably lower than those required for their material failure, so that the stability is mainly due to their shape and self weight. These aspects allowed in the past the simple realization of construction models in a reduced scale in order to assess the stability. As the history has pointed out, the behaviour of constructions is strongly linked to the workmanship and the good realization of the construction details. Local or global collapse can occur in fact due to pathologies arising during the construction or to bad realization of construction details. This paper deals with this last aspect, examining three different masonry buildings: the first one is a brick masonry building in Bologna: San Barbaziano Church, the others are two Roman domus in two different archaelogical sites in Campania: Villa Regina (Boscoreale, Napoli) and Villa dei Misteri (Pompeii, Napoli). The defects have been divided into two classes: structural defects and non structural ones. It is shown that structural defects can cause a global damage and could involve significant interventions.
