The Vulnerability and Territorial Management section deals with the vulnerability assessment of structures and infrastructures at various geographical scales: single structures, urban, regional and national. The section is composed of experts in structural analysis who develop analytical methods ranging from advanced nonlinear finite element analysis of structures to simplified methodologies that describe the behaviour of structures at an urban scale in probabilistic terms. Furthermore, an important task like gathering and post processing field data, used for instance to characterize existing building stocks, site conditions, observed damage, is also assigned to this section. The results of the vulnerability studies are then combined with seismic hazard, which describes the severity of ground shaking, in order to define seismic risk and expected damage or losses.
In order to aid the treatment of data and presentation of results, which are used to define prioritization schemes for structural retrofitting and other seismic risk mitigation measures, the section has also built up significant experience in the development of GIS-based applications, desktop and web-based. The WebGIS platforms developed allow to view and export exposure, hazard and vulnerability data of each minimum unity for the seismic risk definition (eg. municipalities, school buildings, bridges) and the results of the risk analysis conducted. In the platform are also available tools for the execution of damage scenarios in real time that accept as input the coordinates of the epicenter, or the fault that is likely to be activated or directly a ShakeMap. The Vulnerability and Territorial Management section has also developed WebGIS platforms which provide for access by multiple users, each with their own role in the process implemented.
The Vulnerability and Territorial Management section has developed two information systems to support the activity of the authorities working in the national building and territorial management. Such systems are accessible via web and allow on one side to upload design data on new structures, retrofitting of existing ones and microzonation studies, and on the other side allows officials to verify all inputs in a fully automatic way. On the basis of design data entered, the procedures implemented by the Vulnerability and Territorial Management section check the compliance of the design with the current code regulation. Another information system establishes the format of the results of microzonation studies on the basis of current regulations, verifies the compliance of the format and transfers the data to the authority.
