This study aimed to investigate a novel slender buckling-restrained knee brace damper (BRKB) for welded and weld-free steel framing systems. The proposed BRKB adopts steel bar cores connected by a central coupler and restrained by tube buckling restrainers with a cover tube supporter. The ...

Evaluation of the use of braces to prevent injury to the knee in collegiate football players. Data were collected in 1984 from seventy-one schools that were members of Division I of the National College Athletic Association and in 1985 from sixty-one of these schools to assess whether the use...
When the displacement was small and in the range of 30–40 mm, the peripheral screws of all specimens began to tilt, and slight buckling occurred at the connection of the transverse bracing and diagonal bracing of all specimens. It was worth mentioning that the screws at the steel strip of...
beam-to-column connectionbuckling-restrained knee bracetrial designreuseThe basic concept of a damage-controlled (DC) structure is that by clearly separating the main frame from the energy absorption members, the main frame is kept within the elastic range and the seismic energy force is ...
Analytical models and a performance-based seismic design procedure were developed for a structure with buckling-restrained knee-braces. The hinge-connected main structural members, such as beams and columns, were designed only for gravity loads, and the knee-braces were designed to resist all the ...
Knee braces located in the corner regions of beams and columns have high potential to be widely used in different structures under wind and earthquake loading. Since it is possible that even such braces experience buckling, some attention has been paid to carry out research on using buckling-...
Buckling modesEnergy dissipationSeismic performanceImportant experimental information on structural performance of effective knee-braced frames was presented.Improved brace member design using controlled buckling mechanism was proposed and validated.Improved design for knee brace to beam connection was proposed....
The benefit of adopting a steel bar is that it enables the downsizing of the knee brace connections between braces and beam flanges. The advantages of tube buckling restrainers include relatively simple implementation for ease of construction and reduced weight compared to mortar-filled buckling res...
Probabilistic performance for gravity-designed steel frame building was evaluated.75 types of Buckling-Restrained Knee Brace (BRKB) models were considered.Using a rapid fragility contour, a seismic retrofit scheme of BRKBs was developed.The building with the optimum BRKBs was satisfied with a code-...
