The project M.E.E.T.I.N.G. aims to define a series of intervention methods for the One of the common characteristics of Adriatic region is that it has history of seismic activities, known to be hazardous to structures and historic buildings that are not resistant to earthquakes.
The research project has the main goal to face in a multidisciplinare and innovative way the problems of the reduction of the seismic risk in industrial and city areas, integrating aspects of seismology, geophysics, geology, geotechnics and structural and numerical calculation.
The project will be structured in two main parts: in first there will be underlined methodological and operative methodologies: the work will produce common guidelines for the mitigation of the seismic risk in industrial and urban areas. During second phase, applicative procedures of the developed methods will be used, testing sites with recorded histories of seismic activity where determined procedures will be applied in a comprehensive way.
Specifically, the guidelines will be divided in a series of chapters pertaining to single aspects that contribute to the definition of seismic risk, which are hazard, vulnerability and exposure. The same guidelines will be finalized to development of aseismic methodologies of planning, eventually to be transferred in the design procedures for countries in the Adriatic area. The guidelines will be generally oriented towards a performance-based approach, offering to designers several methods of analysis, that will vary from simple to sophisticated; they will be sufficiently generic, to ensure the correct application in various urban and industrial areas. that differ in economic and social typology, environment and seismic hazard.
Therefore, the general goals of the project are:
- Writing of guidelines for the mitigation of the seismic risk in urban areas and in industrial regional districts (with emphasis on historic buildings and areas);
- Application of the proposed methodologies in selected areas.
The latter will demand:
a. the choice of testing sites and examples to develop, that will be selected in the area of Termoli, an urban area with important industrial district, classified as a seismic area only after the 2002 Molise earthquake; and in the city of Zagreb and Dubrovnik where through history has been recorded intense seismic activity.
b. the definition of the expected seismic motion, based on models of potentially active seismic sources and models of propagation at regional and local scale;
c. the definition of the site effects using with the different methodologies and the realization of microzonation maps based on the levels of reliability of the geological-geotechnical database;
d. the development of integrated procedures of risk assessment for complex systems, including all the physical and structural component of the system, particularly each single structure, their interaction with the physical environment, the importance of possible alternatives in order to guarantee the functionality of the system, the importance of the induced damage;
e. the development of relatively simple models for the evaluation of the vulnerability of the components of the systems, including an estimate of the effects of the variability of the parameters used;
f. the development and the evaluation of methods of reduction of the vulnerability, based on innovative techniques, including soil treatment, isolation techniques and artificial dissipation and use of advanced composed materials;
g. the evaluation of damage scenarios for the analysed real cases, with an estimation of the economic damages, the evacuations and the human losses.
