MAURER MAURER SIP-Adaptive 2nd generation of Sliding Isolation Pendulums

MAURER SIP-Adaptive >> MAURER SIP-Adaptive >> INNOVATIVE SEISMIC ISOLATION Sliding Isolation Pendulums (SIP) shift the natural period of the structure out of the period range of high seismic energy by their large radius of curvature and further reduce the structural acceleration response by their damping. The new SIP-Adaptive represents a further development of the MAURER SIP series. The adaptive characteristics of the SIP-Adaptive allow for generating optimum isolation of civil structures independent of intensity (PGA) and frequency of earthquakes. >> Schematic cross section of...

>> New Acropolis Museum, Athens / Greece Task: Structural isolation for protection against earthquakes for a 33.000-ton new building. Scope of the project: 98 pcs. MAURER MSM® Sliding Pendulum Bearings with upper sliding plate (SIP) for up to 13.6 MN of superimposed load and ± 255 mm of movement. >> Djamaa El Djazair Mosque, Algiers / Algeria Task: The maximum seismic acceleration on the 145-meter long, 145-meter wide and 65-meter tall main building is around 0.65 g. Even at this acceleration, the structure is protected and does not sustain any significant damage. Scope of the project: 246...
