  2. Buckling-restrained braced frame - Wikipedia

    en.wikipedia.org/wiki/Buckling-restrained_braced...

    Buckling-restrained braced frame (BRBF) is a structural steel frame that provides lateral resistance to buckling, particularly during seismic activity. [1] The BRBF is typically a special case of a concentrically braced frame. Tests have demonstrated BRBF systems are highly effective for energy dissipation, while being vulnerable to large ...

  3. Buckling-restrained brace - Wikipedia

    en.wikipedia.org/wiki/Buckling-restrained_brace

    A buckling-restrained brace (BRB) is a structural brace in a building, designed to allow the building to withstand cyclical lateral loadings, typically earthquake-induced loading. It consists of a slender steel core, a concrete casing designed to continuously support the core and prevent buckling under axial compression , and an interface ...

  4. Earthquake engineering - Wikipedia

    en.wikipedia.org/wiki/Earthquake_engineering

    Seismic performance assessment or seismic structural analysis is a powerful tool of earthquake engineering which utilizes detailed modelling of the structure together with methods of structural analysis to gain a better understanding of seismic performance of building and non-building structures. The technique as a formal concept is a ...

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

    In EN 1998-4, principles and application rules for the seismic design of the structural aspects of facilities composed of above-ground and buried pipeline systems and of storage tanks of different types and uses, as well as for independent items, such as for example single water towers serving a specific purpose or groups of silos enclosing ...

  6. Seismic analysis - Wikipedia

    en.wikipedia.org/wiki/Seismic_analysis

    Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design , earthquake engineering or structural assessment and retrofit (see structural engineering ) in regions where earthquakes are prevalent.

  7. Seismic retrofit - Wikipedia

    en.wikipedia.org/wiki/Seismic_retrofit

    Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged.

  8. Seismic loading - Wikipedia

    en.wikipedia.org/wiki/Seismic_loading

    Seismic loading is one of the basic concepts of earthquake engineering which means application of an earthquake-generated agitation [1] to a structure. It happens at contact surfaces of a structure either with the ground, [ 2 ] or with adjacent structures, [ 3 ] or with gravity waves from tsunami .

  9. 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 ...
