schloroprenerubberisarelativelynewmaterial,ageingtestsareperformedaccordingtoI188.
he following reference list shows projects with permanently installed elastomeric bearings:
58 storey building
Bedrock or hard soil
Weak clay 310 m
Sand or stiffer
clay 1025 m
1235 m piles
Excavation depth 23 m
Elastic element
A controlled mix of both deep andshallow foundation
When the elastic elements are compressed, the
total load from the building will be balanced betweenpile load and accumulated ground pressure.
The ground structure will be designed with full
soil-structure interaction, together with the bearingcapacity of the piles.
