Şişli & Göztepe Hospitals in Istanbul

The Istanbul hospitals in Şişli and Göztepe were pilot projects for the planning of earthquake-proof hospitals in Türkiye. Werner Sobek was commissioned with the structural engineering of these exciting projects.

Earthquake Safety through Basic Insulation

Basic isolation ensures that the hospital can be put back into operation immediately, even after a severe earthquake. In addition, all systems required for hospital operations remain fully functional even in the event of strong seismic shocks.

In the basic insulation, the building is isolated from the surrounding soil and has surrounding supporting wall constructions. In addition, special bearing constructions (so-called triple friction pendulum bearings) were installed on the lowest floor, which separate the building foundation from the parts of the building above the bearings. This provides an additional level of insulation within the building.

The earthquake resistance was verified using extensive non-linear time-history analyses on a three-dimensional building model. The two hospitals were rebuilt in stages during ongoing operations.
