“…Based on the results of seismic evaluation studies, it is very often required the seismic retroffiting or at least the seismic upgrading of masonry constructions. Therefore, in order to avoid building collapses and consequent human victims, over the years various traditional (Italian Ministers Council Presidency Decree (DPCM), 2011 ;Formisano, 2014Formisano, , 2017Formisano and Marzo, 2017) and innovative (Bertolesi et al, 2017;Mosoarca et al, 2017;Ramaglia et al, 2018) intervention techniques have been developed.…”

Italian buildings are mainly represented by unreinforced masonry (URM) constructions, which were mostly built before 1970, often without respecting seismic design criteria. The main objective of Italian designers is, therefore, to retrofit these buildings in order to improve their safety under earthquake, as well as to preserve the memory of the ancient building art. In addition, the assessment of the building energetic efficiency is nowadays a very pressing need for designers and practitioners. Energetic efficiency represents the capacity to optimize the consumption of energy resources in order to reach prefixed requirements for the environment protection . This paper shows both seismic and energetic retrofitting interventions on a residential URM building typical of the constructive practice in the South Italy. Initially, the building characterization under geometrical and structural viewpoints is done. Subsequently, the seismic vulnerability verification is performed with unsatisfactory results, so requiring upgrading or retrofitting interventions. Moreover, with the aim to increase living comfort and energy efficiency, energetic upgrading interventions, aimed at decreasing the building transmittance, are proposed. Seismic and energetic interventions are then computed from the economic point of view in order to evaluate the financial contributions foreseen by the Italian 2018 Balance Law through the Sismabonus and Ecobonus tools, respectively. Finally, the study proposes a global performance index able to take into account contemporary the seismic, energetic, and economic benefits deriving from retrofitting interventions applied on the inspected residential building.

“…8. In the longitudinal direction, the walls occupy 21.65% of the built area, and in the transverse direction, 19.97% [4]. During the communist period, the building housed the Pioneer House, but it was later abandoned and fell into an advanced state of decay due to post-December events.…”

The subject addresses heritage objects that are subject to degradation processes caused by both natural and anthropogenic factors. One of the current solutions is directed towards a varied range of scientific instruments, thus facilitating the analysis and diagnosis of the concerned buildings, contributing also to the identification of materials and techniques used and providing information about any previous interventions of conservation attempts. Recent visualization methods used in the diagnosis and consolidation of historic structures can utilize both three-dimensional laser scanning technology and laser interferometry as a diagnostic method, as well as alternative methods such electrometry, magnetometry and ground penetrating radar devices. The subject aims to address how heritage objects can be secured using 3D scanning technologies. The case studies were conducted on the Bezdin Monastery Complex, the ”Saint Martyr Gheorghe” Church, the ”Saint Martyr Filimon” Monastery and the former Metropolitan Summer Residence in Sibiu. The selected case studies illustrate the methodology for obtaining and processing field data, as well as the use of this data in the diagnosis process and in selecting appropriate consolidation options for these historical structures based on obtained results. These technologies have provided specialists with the possibility of extracting vital information both in the diagnostic phase and throughout the implementation of restoration works. Advanced scanning technologies of today have enabled the creation of a database with the capability of providing pertinent information about a building’s past, starting from its initial stage, up to the completion of execution works, which significantly aids in facilitating the process of diagnostic analysis and structural calculation.

“…Therefore, simplified procedures for simulated modal identification analysis of the inspected buildings are developed. In this regard, many mechanical models are analyzed in several scientific papers [4,5,9], where the uncertainties related to vulnerability factors are often considered to quantify the seismic response of the entire aggregate and to set up appropriate risk mitigation procedures [24,25].…”

The present research aims at investigating the vibration period of structural units (SUs) of a typical masonry aggregate located in the historical center of Mirandola, a municipality in the province of Modena. The clustered building consists of eighteen SUs mutually interconnected to each other, which are characterized by solid brick walls and deformable floors. First of all, non-linear static analyses are performed by adopting the 3Muri software focusing on two distinct modelling techniques concerning the analyzed SUs in isolated and clustered configurations. Congruently to the procedure adopted, in order to evaluate a reliable seismic structural response of the SUs arranged in aggregate conditions, the contribution in terms of stiffness and mass derived from adjacent buildings is considered. The analysis results are represented in terms of risk factor, stiffness, and ductility. Secondly, the eigenvalue analysis is faithfully developed to identify the main vibration modes of the investigated SUs by proposing an empirical formulation, that allows for predicting the vibration period of structural units placed in aggregate configuration starting from the corresponding isolated ones. Finally, fragility functions are derived for both the heading and intermediate SUs to point out the expected damages under earthquakes with different intensities.
