Seismic Vulnerability Assessment
Analysis of structural behaviour under seismic actions, defining strengthening measures that ensure safety and performance.
Understanding Seismic Behaviour.
Seismic Vulnerability Assessment enables the evaluation of how an existing building responds to seismic actions and the identification of its principal weaknesses.
Through structural modelling and seismic performance analysis, we assess the load-bearing capacity of the structure, the most probable collapse mechanisms and the associated level of risk.
This service provides a robust technical basis for defining risk mitigation and seismic strengthening strategies, tailored to the characteristics of the building and applicable regulatory requirements.
When to use
When assessing the seismic risk of existing buildings, particularly in areas of high seismic hazard.
Prior to conservation interventions in existing structures.
For essential or strategic buildings (schools, hospitals, critical infrastructure).
To support decision-making regarding the need for seismic strengthening.
As part of property enhancement processes or to comply with legal and regulatory requirements.
Seismic assessment is fundamental to reducing risk and enhancing building safety.
Identification of vulnerabilities
Identification of structural elements and failure mechanisms resulting from seismic action.
Seismic risk reduction
Support in defining effective damage mitigation and collapse prevention strategies.
Decision support
Clear technical information to support decisions regarding strengthening, rehabilitation or alternative intervention measures.
Protection of life and heritage
Contributes to occupant safety and the preservation of built heritage.
Basis for strengthening design
Provides the necessary data for the development of appropriate seismic strengthening projects.
Enhanced confidence, resilience and market value
Improves resilience, user confidence and the overall market value of assets.
