Bosphorus Seismic Tower
A base-isolated mixed-use tower engineered for Istanbul's extreme seismic hazard.

Standing near one of the most active fault systems in Europe, Bosphorus Seismic Tower is a 48-storey mixed-use development engineered to remain fully operational after a major earthquake.
A base-isolation system of triple-friction-pendulum bearings decouples the superstructure from ground motion, cutting the peak acceleration transferred into the building by roughly 40%.
The design was verified through nonlinear time-history analysis against a suite of site-specific ground motions, pairing the isolation layer with supplemental viscous dampers to control residual drift.
