Special Issue Information

Dear Colleagues,

The latest seismic events have once again highlighted the extreme fragility of real estate assets, and, in particular, of historic centers which often contain an invaluable cultural heritage. The dramatic nature of events gave further impetus to the already considerable efforts of the scientific world in carrying out the numerous ongoing initiatives at a scientific, technical, and regulatory level.


The problem of protecting the built environment in earthquake-prone regions involves not only an optimal design and construction of new facilities, but also the upgrading and rehabilitation of existing structures, including heritage buildings. The type of highly specialized retrofitting employed to protect built heritage is an important area of research.


Today, in fact, the preservation of civil structures and, especially, architectural heritage represents a considerable concern in many countries, especially due to the decay and to the risk associated to natural extreme actions, such as earthquakes. An evaluation supported by nondestructive methods and techniques is especially important to safely survey and report on the structural health of ancient buildings and architectural heritage. Heavy interventions can be avoided if a rigorous preventive structural health assessment is enforced in structures that have often suffered many changes in time. With this aim, the Special Issue focuses on the use of:

 

  • Nondestructive methods based on sensor technology, data processing techniques, and analysis methods to get an extensive knowledge of the structural health and the operative conditions of buildings and structures;
  • Choice of the optimal type of intervention for improving the performance of the structure in a seismic area, thus leading to the most appropriate control strategy and refurbishment provision, including innovative protection technologies, as effective solutions to respond to the constantly increasing performance requirements in structural design and rehabilitation.

 

At the same time, the Issue invites papers on new and challenging research perspectives related to the improvement of the energy efficiency capacity of structures, very important today to reduce the energy costs of a building.


The objective of this Special Issue is to provide readers with the latest research and application achievements in the field, including emerging aspects in analytical and finite element modeling, design, testing, and practical implementation studies.


We encourage and invite authors to submit original research articles as well as review papers.


Multidisciplinary papers are especially encouraged. Potential topics include but are not limited to:

- Seismic hazard and seismic risk;

- Structural control;

- Techniques for the forecast of seismic excitation;

- Vulnerability of historical and contemporaneous structures;

This paper aims to investigate the seismic vulnerability of key port infrastructure components by using the outcomes of advanced numerical analysis. For the first time, to the best knowledge of the authors, a pile-supported wharf structure, the soil deposits where the wharf lies, and a crane typically operating on the wharf are numerically modelled as a combined system. The starting point for building the numerical model is the main components of strategic facilities at the port of Gioia Tauro (Italy), which is a strategic hub for container traffic located in one of the most seismically active regions of the Mediterranean Sea. Based on the results obtained from two-dimensional (2D) dynamic analyses, fragility curves were developed for single port components and the wharf-crane-soil system. A scenario-based seismic damage assessment was then exemplified to compare the predictions resulting from the fragility model presented in this work with the relevant data available in the literature. It turns out that, besides some inevitable variations, expected damage percentages were in general agreement. As the main contribution of this work, derived fragility curves might be adopted as an effective tool for rapid evaluation of the seismic performance of port components during the development of strategies for risk mitigation and also the emergency management in case of an earthquake.

Structural health monitoring is a crucial issue in areas with different hazard sources, such as Italy. Among non-invasive monitoring techniques, remote sensing provides useful information in supporting the management process and safety evaluations, reducing the impact of disturbances on the functionality of construction systems. The ground displacement time-series based on the analysis of Differential Interferometric Synthetic Aperture Radar (DInSAR) measurements, as well as the information about the geology of the area and the geometry of the construction under monitoring, provides useful data for the built environment’s structural assessment. This paper focuses on the structural monitoring and damage assessment of constructions based on the GIS integration of DInSAR measurements, geological investigation, historical surveys and 3D modeling. The methodology is applied to the residential area of Valco San Paolo in the city of Rome (Italy). Once the geological interpretation has confirmed the results of the DInSAR measurements, a quick damage assessment that considers all the possible conditions of the pre-existing damage at the time zero of the monitoring is shown for a damaged manufact in the area. The presented results highlight how the strategy to correlate the DInSAR-monitored ground settlements with the damage scales allows potentially to monitor continuous construction systems.

Several methodologies for assessing seismic risk extract information from the statistical relationship between the intensity of ground motions and the structural response. The first group is represented by intensity measures (IMs) whilst the latter by engineering demand parameters (EDPs). The higher the correlation between them, the lesser the uncertainty in estimating seismic damage in structures. In general, IMs are composed by either a single (scalar-based IMs) or a group of features of both the ground motion and the structure (vector-valued IMs); the latter category provides higher efficiency to explain EDPs when compared to the first one. This paper explores how to find new vector-valued IMs, which are highly correlated with EDPs, by means of multi-regression analysis. To do so, probabilistic nonlinear dynamic analyses have been performed by considering a seven-story reinforced concrete building as a testbed. At a first stage, 30 scalar-based IMs have been correlated with 4 EDPs (i.e., 120 groups of IM-EDP pairs have been studied). Afterwards, the structural responses have been classified as elastic, inelastic and a combination of both. It has been analyzed how efficiency behaves when making these classifications. Then, 435 vector-valued IMs have been created to enhance the predictability of the scalar EDPs (i.e., 1740 groups of IM-EDP pairs have been analyzed). Again, the most efficient IMs have been identified. Sufficiency, which is another statistical property desired in IMs, has also been examined. Results show that the efficiency and sufficiency to predict the structural response increase when considering vector-valued IMs. This sophistication has important consequences in terms of design or assessment of civil structures.

A new section of a study on innovative anti-seismic design strategies of precast reinforced concrete structures is presented herein. The solution conceived in this new step of the study consists in seismically isolating the building roof and incorporating girder-to-column dissipative connections. Two different types of dissipaters are considered for installation in the latter, i.e., fluid viscous spring-dampers and triangle-shaped added-damping-and-stiffness steel yielding devices. A benchmark building, designed according to a traditional ductility-based approach at a previous step of the study, is redesigned by assuming the two alternative dissipative connection technologies. Sizing criteria and details of both solutions are discussed, along with the results of the time–history analyses carried out to assess their performance up to the maximum considered normative earthquake level, and a comparative cost evaluation with the traditional design is offered.

In the present paper a new and innovative way to approach the regeneration of public buildings and public housing is proposed. It consists in a dissipative steel frame to reduce the displacement demand and to improve the energy efficiency of a real existing structure, inserting buckling-restrained axial dampers (BRAD) type dissipative braces. This system is adaptable to any construction made of reinforced concrete frames and improves energy efficiency and earthquake-resistant performance; moreover, it upgrades the aesthetics of buildings and the quality of life for the users. In fact, the system is capable of assuming different and pleasant architectural shapes offering benefits in terms of earthquake-resistant performance, energy saving, and energy production from renewable sources. The attention to the aesthetic results renders the intervention a redevelopment strategy not only on an architectural scale, but also in the urban contexts for degraded and marginalized suburbs. The performances of the proposed kit were evaluated on a case study consisting in a social house located in the south of Italy. Numerical analyses have been carried out and the results have been reported both from the seismic protection and energy efficiency points of view. As a result, the produced renewable energy from the retrofitting system and the building seismic capacity increased. A rapid and precise control process, able to return a suitable structural dimensioning of the frame, according to the different application contexts, is finally proposed. Full article
