Our client is based in locations across the globe and needed additional accommodation within its secure compound in a city where the risk of terrorist attack is high. They asked our Advanced Technology & Research Centre to design an extra floor for an existing building which would remain safe in the event of blasts and earthquakes.
Modelling analysis proves safety of design
We designed a steel-frame extension which is both ductile and lightweight. Seismic as well as non-linear time history calculations were then applied to model how the structure would respond in the event of both earthquake and blast. Our analysis proved that, while the building would sustain damage, it would remain stable and safe.
In this case, an additional inspection was required to verify the current status of the building. This was because some years previously, strengthening measures had been recommended for the original building. To ensure they had been implemented effectively, a member of our team visited the compound to inspect the building.
“Nothing was left to chance. Our solution integrated seismic and blast risk as well as on-the-ground assessment of the existing building,” said Peter Flink, Structural Engineer, Advanced Technology & Research.
In addition, our non-linear time history analysis is highly precise and proves there is more strength in the design than would have been identified through other methods, adding value for our client.
