Evaluate and mitigate the seismic vulnerability of your civil engineering structures

Your need:

The National Framework for Action for Seismic Risk Prevention (CAPRiS) calls on territorial managers to reduce the vulnerability of their heritage, the only lever to mitigate the impact of seismic risk.

Evaluation, followed by targeted operations to reduce this vulnerability, improves the resilience of your infrastructures to seismic hazards, while controlling the cost.

Cerema supports you in prioritizing structures to be diagnosed, defining and implementing reinforcement techniques adapted to the challenges.

• How to evaluate the level of exposure and vulnerability of your structures to seismic hazards?
• Which structures to diagnose and reinforce as a priority?
• What level of performance to aim for and at what cost?
• What technical solutions to implement and how to justify them?

Cerema's response:

• Seismic risk studies at the global scale of your heritage
• Preliminary evaluation of the sensitivity of structures by calculating vulnerability indices
• Quantification of hazards (vibrations, gravitational risks, soil liquefaction, building collapse on roads...) and evaluation of the response (or risk of collapse) of structures for dif…
