Description du projet
Accroître la résilience face aux risques sismiques
L’amélioration de la résilience et de la durabilité des communautés face aux tremblements de terre, [passe par la réduction de vulnérabilité des structures existantes et l’amélioration de la conception des nouvelles structures. Financé par le programme Actions Marie Skłodowska-Curie, le projet KaIROS souhaite proposer des méthodes avancées de réduction des risques sismiques à l’échelle mondiale. Cette initiative permettra de développer des modules qui intègrent des connaissances novatrices et de nouvelles avancées, pour l’élaboration d’un outil d’évaluation des risques robuste et efficace. L’outil peut fournir des courbes de dommages probabilistes pour une matrice complète de typologie de bâtiments. Les outils de KaIROS peuvent également être utilisés l’analyse de mesures spécifiques de renforcement et de protection des structures, et permettra de formuler des recommandations concernant le renforcement, la modernisation et la conception des bâtiments. Ils peuvent en outre être exploités pour développer des coefficients simplifiés qui tiennent compte de la directionnalité et des effets d’affaiblissement des dommages physiques anticipés.
Objectif
KaIROS proposal focuses on earthquake disasters; its main purpose is to provide beyond-state-of-the-art approaches to reduce seismic risk worldwide. That is, keeping and increasing the opportunities for resilience and the sustainability of communities against earthquakes. The key to reducing seismic risk is decreasing the vulnerability of existing structures and providing new insights to improve the design of new structures. Thus, main specific goals and modules are inventory, assessment, strengthening and regulations. Each module embodies state-of-the-art knowledge and new advances to form a robust and efficient tool for risk assessment. Concerning inventory, a new comprehensive BTM will include the most relevant building types around the world. The assessment tool will be based on fully probabilistic Incremental dynamic analysis of realistic structural models subjected to realistic seismic actions, so that the simulation results approach real outcomes. Thus, an innovative outcome of KaIROS is that it will provide probabilistic damage curves for the enhanced BTM. Specific measures related to reinforcement and/or to protection devices will be analyzed within the Strengthening module. Concerning Regulations, the main contributions will be associated with specific recommendations for strengthening, retrofitting and designing buildings. In addition, simplified coefficients allowing considering the directionality and weakening effects in the expected physical damage will be developed. KaIROS is sensitive to the gender dimension of natural disasters and a special module will investigate this issue. An open access soft-ware that can be used to assess the expected damage at urban level by considering several structural typologies and to perform cost-benefit analyses of strengthening measures, amongst many other possibilities, will be created and promoted. Special attention will be devoted to dissemination so that policy-makers and stakeholders can benefit from KaIROS.
