Among the objectives:

• development of structural vulnerability models, for the purpose of risk assessment analyses, for hazards other than seismic hazards and for cascading effects of industrial accidents (so-called NaTech);
• development of fragility curves for measures of intensity for the hazards considered through a strongly interdisciplinary approach.

Among the objectives:

• continuing the work started in previous years, taking the significant results described below as acquired;
• broadening the range of products, with reference to both the types of artefacts and the risk issues addressed, in particular:
• developing risk maps for specialised buildings/constructions (schools and churches, potentially hospitals, warehouses and bridges);
• developing procedures for the elaboration of seismic damage scenarios and their representation in an effective and functional way for different Civil Protection purposes (OELF, post-event), to be implemented in the SIGE Plus platform;
• continuing the survey activities of the built environment, through the compilation of CARTIS forms (CARTIS Compartment, CARTIS Building, CARTIS Great Lights, CARTIS Churches) and to develop new forms, for the collection of information on the other analysed buildings (CARTIS Schools, derived from CARTIS Building) and hospitals (CARTIS Hospitals).

Among the objectives:

• developing sustainable intervention strategies for existing Italian buildings, with a view to integrated redevelopment aimed at the contextual improvement of the building’s structural, seismic, energy and functional performance, and which considers the impact components (economic, social, …) in the project;
• providing not only technical solutions for interventions, but also useful tools for the correct design and evaluation of interventions on existing buildings and special structures (churches and bridges).

Among the objectives:

• develop, test and refine further algorithms for analysing satellite interferometric data for new survey areas, including using new satellite constellations and multi-frequency techniques to improve data robustness and integrability;
• Develop techniques and protocols for on-site monitoring for the integration of data collected in the field, with different types of instrumentation, in order to (i) obtain a comprehensive and reliable view of the health status of the monitored structures and infrastructures; (ii) assess performance and applicability ranges; (iii) define criteria for determining attention and alarm thresholds.

Among the objectives:

• analysing the post-earthquake reconstruction process in central Italy 2016-2017 focusing on similarities and differences with the post-earthquake reconstruction in Abruzzo 2009;
• Evaluating the specific impact of local construction techniques (specific to each region) on the severity and extent of damage;
• Extending the study of earthquake damage and reconstruction processes to the international scene;
• examining the effectiveness of seismic strengthening interventions on the seismic response of buildings;
• Using advanced Machine Learning (ML) and Image Analysis techniques for post-earthquake data analysis.

Among the objectives:

• continuing activities in support of the SNPC, mainly in the framework of the INR (I don’t take risk) campaign, on the macro-theme of information to the population with particular reference to seismic risk mitigation and in relation to other natural and man-made risks;
• realising useful materials to promote the dissemination of seismic and structural engineering activities and results, in particular towards the school world, via the Internet (e.g. ReLUIS website) or other social channels.

Among the objectives:

• Improving the sharing and dissemination capabilities of ReLUIS experimental results and products.

Among the objectives:

• developing local/global capacity models for the definition of limit states of structural masonry;
• Analysis and verification of complex systems (aggregate units, large building complexes, mixed masonry structures and other technologies) and preparation of reference case studies/examples;
• developing local and global capacity models for the definition of limit states of non-structural masonry (infills, partitions);
• Evaluating verification methods in special cases of masonry structures sensitive to the vertical earthquake component.

Among the objectives:

• verifying the applicability and inclusion in the updates of the Technical Standards for Construction of the new proposals contained in the 2nd generation EC2 and EC8, and also in view of a future transposition of the Eurocodes into the Italian regulatory framework, and proposing application methods and design guidelines for a correct and effective application of the standards;
• Developing accurate formulations for determining the connection capacity of precast constructions under different damage conditions, which can be translated into special guidelines.

Among the objectives:

• streamlining activities on related topics, compared to the previous EP DPC-ReLUIS 2022-23, by including wood and steel-wood composite structures;
• propose improvements (updates) to the current regulatory rules, also in the light of the development of the second generation of structural Eurocodes;
• developing pre-normative guidelines;
• making design support tools available;
• producing application examples to support the application of standards, guidelines and design tools.

Among the objectives:

• Defining principles, performance indicators and metrics for sustainability, understood as safety, reliability, eco-efficiency, functionality, robustness and resilience in the life cycle;
• developing degradation models capable of incorporating the main ageing and damage phenomena;
• implementing structural design criteria taking into account performance requirements over the entire life cycle;
• Extending the criteria and methods developed for individual works to assess the performance of groups of works on an urban and infrastructure scale.

Among the objectives:

• providing regulatory and/or pre-normative contributions in relation to the use of innovative and green structural materials, in order to contribute to the sustainability of buildings and new constructions, in terms of safety, durability, low environmental impact;
• studying long-fibre (FRCM), short-fibre (FRC, FRM) inorganic matrix composite materials and Composite Reinforced Mortar (CRM) systems for work on existing buildings;
• evaluating the advantages and disadvantages of using non-metallic reinforcement (FRP) in reinforced concrete structures;
• investigating the usability of green mortars/concretes, i.e. made from recycled materials and/or with low environmental impact binders (alkaline-activated binders – geopolymeric, sulphur-aluminous cements), as well as highly durable concretes made with the addition of nanomaterials.

Among the objectives:

• gaining a better understanding of the behaviour of isolation and dissipation systems in existing buildings;
• developing more effective maintenance, monitoring and control procedures;
• providing input for regulatory updates for the use of isolation and dissipation systems, including unconventional ones;
• proposing more robust and optimised design methods;
• proposing new unconventional systems that are also cheaper than the current ones in order to further stimulate the use of these technologies.

Among the objectives:

• investigating issues concerning site seismic stability problems, dealing with both liquefaction and slope stability, and those of soil-structure interaction, focusing mainly on the foundations of buildings and viaducts, bridges;
• providing competent contributions for the purposes of both seismic risk management and the study of related scenarios, and activities for the preparation of Italian technical regulations and those functional to the transposition of European regulatory products, also interacting strongly with other WPs carrying out complementary activities or involving important geotechnical aspects.

 Among the objectives:

• selecting, within the framework of the ongoing scientific activity, those topics concerning the structural safety of non-structural components that are or will soon be at an adequate maturity level to be included, within the term of the project duration, in an officially recognised body of standards in the current building regulations;
• carrying out an experimental campaign for the evaluation of the seismic response of vertical partition elements subject to bidirectional seismic actions, thanks to the availability of a specific piece of equipment, specially designed by one of the UR’s and unique in Europe.

Among the objectives:

• Identifying, on an international scale, the approaches with which seismic actions in standards relate to seismic hazard models and the constraints for applying Seismic hazard models in the Italian regulatory context;
• Defining the relationship between detailed studies for individual sites, simplified procedures for assessing amplification factors in seismic regulations and seismic microzonation studies;
• Defining criteria for the selection of multi-component, horizontal and vertical accelerograms.
