  2. Seismic base isolation - Wikipedia

    en.wikipedia.org/wiki/Seismic_base_isolation

    Seismic base isolation, also known as base isolation, [3] or base isolation system, [4] is one of the most popular means of protecting a structure against earthquake forces. [5] It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus ...

  3. Eurocode 8: Design of structures for earthquake resistance

    en.wikipedia.org/wiki/Eurocode_8:_Design_of...

    Section 7: Specific rules for composite steel-concrete buildings; Section 8: Specific rules for timber buildings; Section 9: Specific rules for masonry buildings. Section 10 contains the fundamental requirements and other relevant aspects of design and safety related to base isolation of structures and specifically to base isolation of buildings.

  4. Metallic roller bearing - Wikipedia

    en.wikipedia.org/wiki/Metallic_roller_bearing

    In earthquake engineering, a metallic roller bearing is a base isolation device which is intended for protection of various building and non-building structures against potentially damaging lateral impacts of strong earthquakes. This bearing support may be adapted, with certain precautions, as a seismic isolator to skyscrapers and buildings on ...

  5. Earthquake-resistant structures - Wikipedia

    en.wikipedia.org/wiki/Earthquake-resistant...

    Concurrent shake-table testing of two or more building models is a vivid, persuasive and effective way to validate earthquake engineering solutions experimentally. Thus, two wooden houses built before adoption of the 1981 Japanese Building Code were moved to E-Defense [5] for testing. One house was reinforced to enhance its seismic resistance ...

  6. Seismic retrofit - Wikipedia

    en.wikipedia.org/wiki/Seismic_retrofit

    Steel or reinforced concrete beams replace the connections to the foundations, while under these, the isolating pads, or base isolators, replace the material removed. While the base isolation tends to restrict transmission of the ground motion to the building, it also keeps the building positioned properly over the foundation. Careful attention ...

  7. Seismic vibration control - Wikipedia

    en.wikipedia.org/wiki/Seismic_vibration_control

    In earthquake engineering, vibration control is a set of technical means aimed to mitigate seismic impacts in building and non-building structures. All seismic vibration control devices may be classified as passive, active or hybrid [1] where: Base isolator being tested at the UCSD Caltrans-SRMD facility

  8. Vibration isolation - Wikipedia

    en.wikipedia.org/wiki/Vibration_isolation

    Base isolators for seismic isolation of buildings, bridges, etc. Base isolators made of layers of neoprene and steel with a low horizontal stiffness are used to lower the natural frequency of the building. Some other base isolators are designed to slide, preventing the transfer of energy from the ground to the building. Tuned mass dampers

  9. Earthquake engineering - Wikipedia

    en.wikipedia.org/wiki/Earthquake_engineering

    Simple roller bearing is a base isolation device which is intended for protection of various building and non-building structures against potentially damaging lateral impacts of strong earthquakes. This metallic bearing support may be adapted, with certain precautions, as a seismic isolator to skyscrapers and buildings on soft ground.
