Abstract. This paper describes a noninvasive investigation conducted in two important churches, namely the Cathedral of Santa Maria Assunta and the church Santa Croce, both placed in Gravina in Puglia (close to Bari, southern Italy). The church of Santa Croce, now deconsecrated, lies below the Cathedral. Therefore, indeed the two churches constitute a unique building body. Moreover, below the church of Santa Croce there are several crypts, only partially known. The prospecting was performed both with a pulsed commercial GPR system and with a prototypal reconfigurable stepped frequency system. The aim was twofold, namely to achieve some information about the monument and to test the prototypal system. The GPR measurements have been also integrated with an IRT investigation performed on part of the vaulted ceiling of the church of Santa Croce, in order to confirm or deny a possible interpretation of some GPR results.

RESUMENEn edificios históricos son conocidos los efectos nocivos de la presencia de humedad en muros, que deteriora detalles de ornamentación, conjuntamente con los componentes de la mampostería que conforma su propia estructura. Es el caso de la Iglesia Nuestra Señora de la Viña (Salta, Argentina), edificio del s. XIX que presentaba manifestaciones patológicas características de las producidas por la presencia de humedad ascendente. Las tareas de recuperación de las superficies exteriores fueron realizadas una vez que el sistema instalado (por electrólisis) deshumidificó los muros. La elevada inversión realizada requiere de un control periódico de la eficacia del sistema. En este trabajo se presentan los fundamentos y los resultados obtenidos con el empleo de georradar como recurso no destructivo para controlar el sistema de deshumidifación, cuya principal ventaja es la de poder detectar en forma precoz a lo largo del tiempo alguna falla en el sistema, evitando en forma indefinida la aparición de nuevas manifestaciones patológicas por humedad ascendente.Palabras clave: patología; mampostería; humedad; radar.ABSTRACTIn historical buildings the harmful effects in masonry due to moisture are well known, as it affects ornamentation and the components of the masonry which is also the building’s structure. That is the case of the church Nuestra Señora de la Viña (Salta, Argenti na), a XIX cent. building which presented typical pathological symptoms caused by rising damp. An electro physical system was installed in order to dehumidificate the masonry and external surfaces were subsequently recovered. This high investment requires a periodical control of the system’s efficiency. This article presents the foundations of and the results obtained by using an impulse radar as a non-destructive resource to control the dehumidification system. Its main advantage is the early detecting of a failure in the system and so avoiding new pathological symptoms caused by rising damp.Keywords: Pathology masonry; moisture; radar.

<p>Horizontal diaphragms play an important role in the seismic behaviour of old buildings, and their behaviour when loaded by in-plane shear has not yet been sufficiently described in literature. The distribution of horizontal forces among bearing walls is strongly dependent on the stiffness of horizontal components and their connections to the vertical structures. The paper focuses on horizontal diaphragms of historic buildings, such as traditional floor systems and feasible intervention technologies for the improvement of their resilience. Experimental behaviour of original and strengthened wooden floors is analysed in order to obtain information on the system performance and supply parameters for use in numerical modelling.</p>

The use of robotic systems, especially multi-rotor aerial vehicles, in the documentation of historical buildings and cultural heritage monuments has become common in recent years. However, the teleoperated robotic systems have significant limitations encouraging the ongoing development of autonomous unmanned aerial vehicles (UAVs). The autonomous robotic platforms provide a more accurate and safe measurement in distant and difficult to access areas than their teleoperated counterpart. Through the use of autonomous aerial robotic systems, access to such places by humans and building of external infrastructures like scaffolding for documentation purposes is no longer necessary. In this work, we aim to present a novel autonomous unmanned aerial vehicle designed for the documentation of hardly attainable areas of historical buildings. The prototype of this robot was tested in several historical monuments comprising scanned objects located in dark and hardly accessible areas in the upper parts of tall naves. This manuscript presents the results from two specific places: the Church of St. Anne and St. Jacob the Great in Stará Voda, and St. Maurice Church in Olomouc, both in the Czech Republic. Finally, we also compare the three-dimensional map obtained with the measurements made by the 3D laser scanner carried onboard UAV against the ones performed by a 3D terrestrial laser scanner.

Abstract Long-term dynamic loads represent a serious factor which compromise the safety and durability of historical buildings. Though the daily traffic may cause only low level vibrations, which an undamaged structure could safely resist, extreme values of traffic loads over longer periods can be critical having as a consequence the initiation of cracks or the growth of existing ones, such that they may endanger the structure. Good maintenance including control measurements or monitoring can aid in early damage detection and timely planning of remedial actions. The preceding statements are supported by an investigation of the effects of ambient vibrations mainly due to traffic loads on the Basilica of the Assumption of the Virgin Mary in Stará Boleslav. Attention is aimed at a structural fault, its rehabilitation and prognosis for the future.

Artistic Assets

Historical buildings in seismic hazard-prone regions need specific measures in safety protection, largely due to the presence of artistic assets and/or decorations, both movable (e.g., statues, pinnacles, etc.) and unmovable (e.g., frescoes, valuable plasters or wall paintings, mosaics, and stuccoes). A correlation of damage between structural systems and artworks is fundamental for defining limit states, which can identify the proper conditions for interventions. Nevertheless, several vulnerability aspects can be identified before a seismic event occurs, the study of which can provide the basic dataset for setting up preventive measures in conservation programs. In this paper, the vulnerability and damage conditions related to structural elements (SE) and unmovable artistic assets (AA) belonging to historical masonry buildings are analysed. Optimized survey forms for the onsite detection of either intrinsic (e.g., compositional) defects or deterioration phenomena for both materials and structure are proposed, and results are provided in a web data system (called DataBAES). This enables us to compare the current levels of vulnerability and damage of AA and SE on a scale of five increasing grades. This procedure has been validated on a series of buildings struck by earthquakes in Italy and can be used for correlations of the seismic behaviour of SE and AA in predictive analyses.
