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 ...
A buckling-restrained brace (BRB) consists of a steel core surrounded by a hollow steel section, coated with a low-friction material, and then grouted with a specialized mortar. The encasing and mortar prohibit the steel core from buckling when in compression, while the coating prevents axial load from being transferred to the encasement, thus ...
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 ...
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 ...
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.
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 ...
This bracing is known by many names such as herringbone strutting, blocking, bridging, and dwanging. Cross bracing on a bridge tower. In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing is usually seen with two diagonal supports placed in an X-shaped manner.
