ABSTRACT:
A connection apparatus includes a frame-side member securable to a steel structural frame, a brace-side member securable to a seismic brace, and a coupling element that secures frame-side and brace-side members to each other. By way of example, the connection element may provide a hinge-type connection, which substantially isolates a seismic brace from nonaxial loads. As another example, the connection element may be a ball-and-socket type connection, which substantially isolates a seismic brace from nonaxial loads and absorbs any shear and moment applied thereto when the seismic brace drifts out of an intended plane of the steel structural frame. The connection element may also include a collar to stabilize the brace-side member and prevent shears and moments from causing the same to buckle in an unintended direction. Methods of installing and using the connection apparatus are also disclosed.
