Seismic Design for Eccentrically Braced Frames (EBFs) Based on IBC & AISC Standards
Eccentrically Braced Frames (EBFs) are a popular structural solution for buildings in seismic regions due to their energy-dissipation capacity and ductility. According to the International Building Code (IBC) and American Institute of Steel Construction (AISC) Seismic Provisions, EBFs combine the stiffness of braced frames with the ductility of moment frames.
Designing EBFs per IBC and AISC requirements involves selecting frame geometry and materials that meet seismic load demands, providing reliable lateral resistance while managing structural forces. The IBC requires EBFs to be designed to ensure stability under extreme conditions, with clear specifications for load combinations and detailing. The AISC Seismic Provisions complement these guidelines, outlining requirements for link beams that dissipate energy during an earthquake, helping to prevent structural damage.
Together, IBC and AISC provide a robust framework for the safe, effective design of EBFs, offering enhanced resilience in earthquake-prone areas.
