Developed by our advanced technology and research team, this gives owners, architects and engineers a framework for resilience-based earthquake.

Key features

Current building codes do not focus on earthquake resilience – the ability of an organization or community to quickly recover after a future large earthquake. Instead they are designed to protect the lives of building occupants. Significant damage to the building structure, architectural components and facades, mechanical/electrical/plumbing (MEP) equipment and building contents is allowable, as long as lives are kept safe.

As such, when a major earthquake strikes an urban region, the financial costs of demolition, repair and restoration of utilities are immense. Indirect losses due to downtime, business interruption, the loss of culture, sense of community, and quality of life can impact communities and hinder recovery for years and even decades after the earthquake.

The Resilience-based Earthquake Design Initiative (REDi™) Rating System, developed by Arup's Advanced Technology and Research team, proposes a framework for owners, architects, and engineers to implement “resilience-based earthquake design”.

It describes design and planning criteria to enable owners to resume business operations and provide liveable conditions quickly after an earthquake, according to their desired resilience objectives. It also presents a loss evaluation methodology for assessing the success of the adopted design and planning measures in meeting the resilience objectives.
