Overview of the project

MULTIRES aims to develop an advanced, harmonised, multi-level framework to assess earthquake risk of existing Reinforced Concrete (RC) buildings in earthquake-prone regions and to design/select practice-oriented, cost-effective, seismic resilience-enhancing solutions (e.g. structural retrofit, risk-transfer products).

The framework will benefit several seismic-prone countries (e.g. Greece, Italy, Romania), for which most of the existing buildings are designed according to pre-seismic codes and where, RC buildings represent the highest share from 1960s onwards (e.g. 48% in Italy). Two levels of analysis refinement will be considered, single buildings vs. building portfolios, specifically tailored to the expected needs/goals of different stakeholders: building owners and government agencies/(re)insurance companies. A coherent treatment of risk and uncertainty in each project’s task will promote dynamic and informed decision-making aiming at seismic resilience.

MULTIRES builds on probabilistic catastrophe risk modelling and seismic performance assessment of existing RC building grounds. State of the art/practice is advanced providing flexible analysis methods for fragility and vulnerability assessment and their implementation tools.

Through world-leading research training and co-development, the project contributes to create a holistic culture of risk awareness and resilience in Europe, reflecting a strong commitment to the Sendai Framework for Disaster Risk Reduction.
