designed steel braced frames provide lateral strength and stiffness, as well as
deformation capacity, such that the structure’s performance is reliable.
Seismic loading can result in large forces in members and their connections, as
well as deformation demands in braces, their connections, and the
beam-to-column connection. Special Concentrically Braced Frames accommodate
frame movement through brace buckling, which can impose additional connection
deformations; this system also benefits from distributed yielding, including
some connection contribution. This presentation will address:
- Designing gussets for strength
- Proportioning gussets for ductility
- Rotation demands at beam-to-column connections
- Accommodating brace buckling in SCBF
- When to worry about the “chevron effect” (and when not to)
- Course will award 1.5 hours of continuing education
- This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.
