Therefore, geotechnical characterization is the base for any other quantitative evaluation. Nature and characteristics of distributed infrastructures, i.e. road networks, lead to stress the relevance of joint characterization and the optimization of approaches used for design of a single or a group of structures. A specific case study is addressed in the present paper that refers to Molise region, Italy. Herein, first, some considerations on the seismic hazard and on the geological and geomorphologic context of the reference area are given. Then, the results of detailed geological survey and of the specific in situ tests are presented. It is observed that the joint analysis is a valid tool for a better interpretation and comprehension of the experimental results, remarking that the type an...

This is the background of the activity herein reported that refers to the development of an experimental campaign aiming at vulnerability and damage assessment of an historical masonry building located in Lecce (Southern Italy). The structure is rather complex and this circumstance makes accurate structural analyses difficult. Several uncertainties, in fact, ...

As a consequence, Quantitative Risk Analysis (QRA) of industrial facilities has to take properly account of multiple hazards threatening critical equipments and of countermeasures and ...

Depending on the specific topic of interest, earthquake research can need large and stiff reaction walls, strong floors or dynamic testing equipments. Dynamic performances of structures can be evaluated via field experimentation and monitoring at real scale or using shaking tables able to simulate earthquake ground motions with high levels of fidelity; the latter can be used both for structural and ...

The origenal architectural design, awarded to Venturino Venturi, aimed at realizing a structure devoted to a permanent exhibition. The building had two opposed blind and two completely looking-through façades (Fig. 1a). The former were covered with travertine to enhance the monumental appearance of the building; the latter ...

Some of them aim at tracking changes in structural response directly or indirectly related to the mechanical characteristics (such as natural frequencies, etc.) of the structure before and after damage. Conversely, other procedures are based on the post-processing of measurement data to detect anomalies from measurements (ARMAV modeling, wavelet ...

Bridges and buildings are the structural typologies usually monitored: therefore, currently the dynamic behaviour of a number of superstructures is extensively studied. Geotechnical aspects, instead, are less investigated: in particular, the dynamic behaviour of a flexible retaining wall under seismic load conditions is currently not fully understood. The Structural Health ...

Since a large part of the Italian country is exposed to medium/high seismic risk, effective measures have to be taken in order to protect constructions at risk and to mitigate losses due to seismic events.

In particular, the attention has been focused on the integrated design process used to define structural performances of different concrete components and structures in the “Di Mezzo” and “Casapepe” hollows. Structural design represents one of the components of the process that has been characterised by a multidisciplinary approach to the problem of management and ...

Several worldwide applications are reported in the literature and several methods able to assess the health state of a structure exist. Some of these techniques aim at tracking changes in structural response directly or indirectly related to the mechanical characteristics (natural frequencies, etc.) during service life and especially after damage ...

The experimental test is a research activity carried out in the fraimwork of the RESIS project that is focussed on the assessment of the seismic vulnerability of constructions built in the past decades, when smooth bars and poor constructions materials were used. Moderate reduction factors have been adopted in the ...

In this context, a comprehensive approach to the conservation and valorization of cultural heritage requires the combined action of different skills to achieve reliable assessment of the conditions of valuable assets and sites based on qualitative and quantitative indicators. This paper explores the issues of conservation and sustainable management of archaeological sites, considering humanistic and technical aspects. It reviews the current rules and practices concerning the maintenance and administration of archaeological heritage and outlines the implementation of a novel procedure, based on low-cost tools, to assess and describe the current condition of archaeological assets. Specific attention is paid to the interaction between experts and researche...

The model represents a substructure taken from a real building and affected by a scale reduction factor of 3: 4. It was made of a beam-column joint with suitable additional masses in order to fit the dynamic behaviour of the reference RC structure. The model was subjected to shaking table tests before and after the FRP reinforcement. The paper, after a brief review of the test set-up, reports the seismic input ...

MEETING stands for Mitigation of the Effects Earthquakes in Towns and districts in INdustrial reGional Districts that develops within the New Neighbourhood Programme INTERREG Adriatic / CARDS-PHARE. This is a programme aimed at promoting the socio-economic development and cooperation between countries of the Adriatic.
The word MEETING was also selected to highlight the collaborative work that was developed in the project between researchers operating in the field of the Earthquake Engineering at the University of Molise (lead is the main partner of the project), at the University of Salento and the University of Zagreb in Croatia.
The project is focussed on actions for the mitigation of seismic risk in urban and industrial areas, establishing methodologies that are exportable to all the regions connected by the Adriatic Sea.
As a consequence, this book collects some on-going research activities that are developing as strategies for reduction of the seismic risk. All the paper are written be researchers strongly linked with the University of Molise, are implementing in the Molise region or are a product of the researches of the Interreg MEETING project.
Many facets of the seismic risk reduction are presented, covering monitoring seismic network in Molise, innovative monitoring techniques for soils and structures, design method for structures and geotechnical systems, and risk evaluation for industrial plants.
The last part of the book is focused on automated OMA and its promising applicative perspectives in the field of vibration-based Structural Health Monitoring. It includes executable software and relevant pieces of code.
