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 ...
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 ...
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 ...
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.
We tested 10 of the best Dutch ovens, including options from Le Creuset, Staub, Lodge, and more. These are our top recommendations for your kitchen.
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 ...
Collectors, also known as drag members, transfer the diaphragm shear to shear walls and other vertical elements of the seismic-force-resisting system. Shear walls are typically made of light framed or braced wood sheathed in shear-resisting material such as plywood or other structurally rigid panels, reinforced concrete , reinforced masonry ...
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 ...
