Great Mosque of Algiers: 500 Years of Protection against Earthquakes

MAURER develops hybrid solution made of pendulum bearings and hydraulic dampers.

Algiers, Munich. The Great Mosque of Algiers (Djamaâ El Djazïr) will be the third biggest in the world and has to last for at least 500 years. Consequently it has to be protected against earthquakes which has to be expected in this region. The challenge was to devise a protection system that protects both structure and humans at small and medium size earthquakes, and also prevents the structure from a collapse in case of the maximum credible earthquake. MAURER developed a protection system consisting of 246 sliding pendulum bearings and 80 adaptive hydraulic dampers.
