Structures under extreme loading

Client: Eurocode 8

Consultant: Professor Ahmed Elghazouli, Department of Civil and Environmental Engineering

Expertise: Seismic assessment and design of buildings to withstand earthquakes

The consultants shared their expertise in seismic assessment and design to support the development of EN1998, also known as Eurocode 8, a European standard regulating seismic design, as well as a number of supporting guides that require expert knowledge in seismic design and other aspects of structural dynamics.

 

The Challenge

Whilst designing a building to withstand earthquakes may not be a common requirement in the UK, for many structural engineers in other countries it’s a vital step in the building process. From the skyscrapers in the Middle East to smaller structures near fault lines, as our buildings have become more ambitious our understanding of how an earthquake will affect them has improved too. Engineers at Imperial were involved in drafting Eurocode 8, the European standard regulating seismic design.

 

The Solution

We engaged Professor Ahmed Elghazouli due to his expert knowledge in seismic design and other aspects of structural dynamics including everything from how structures behave under extreme loads such as blast explosions and building fires, and the best approaches to accommodate the consequences of such events in the design philosophy, to the effects of smaller vibrations – pedestrians walking over a footbridge for example or the vibrations in the floor of a large function hall or office building.

 

The Impact

EN1998, also known as Eurocode 8: Design of structures for earthquake resistance is the European Standard for the design of structures in seismic zones, as approved by the European Committee for Standardization (CEN).

 

Professor Ahmed Elghazouli comments:

The consultancies I’m involved in are always on the border between advanced assessment and research – there’s a direct interaction between the two. It’s not the kind of knowledge usually held within a typical design firm. Advanced seismic design normally stems from research. The combination of our engineering expertise, testing facilities and computational modelling means we can offer a completely comprehensive service to clients.

Putting science into Sci-Fi

When Left Bank Pictures (producers of The Crown and Lost) were looking for someone to give their Sci fi adventure, ORIGIN, a touch of realism - they called upon Imperial Consultants. Thanks to his previous work with filmmakers, writers and artists, they were introduced to Dr Roberto Trotta, a theoretical cosmologist renowned for taking on the unusual - and gifted in translating ‘science-speak’ into layman’s terms. read more

Informing the debate on Britain’s electricity system

The electricity sector is currently undergoing unprecedented changes, including obligations to decarbonise and pressure to keep bills down. With old coal being driven off the system, new nuclear given the go-ahead, prices reaching new highs and lows, and clean energy overtaking fossil fuels for the first time, there is an increasing need for a strong evidence base and robust analysis. read more
