Seismic eccentrically braced frames
WebA braced frame is a structural system designed to resist wind and earthquake forces. Members in a braced frame are not allowed to sway laterally (which can be done using shear wall or a diagonal steel sections, similar to a truss ). Types of braced frame [ edit] The John Hancock Center is a braced tube structure. Most braced frames are concentric.

WebConcentrically braced frames (CBFs) are elastically designed as one vertical truss system to resist lateral loads through axial brace members when they are introduced. The explicit capacity-design approach has been fully incorporated into the newest seismic provisions for structural steel buildings. WebThere are two main varieties of braced frames – concentric and eccentric. Concentric bracing. Concentric bracing consists of diagonal braces located in the plane of the frame. Both ends of the brace join at the end points of …
