Abstract
EBFs employ the braces with deliberately large eccentricities with respect to the beam-column joint. The eccentricity is introduced to provide a ductile fuse which will prevent hazardous brace buckling at extreme loads. The axial forces in the braces are transmitted to the columns through bending and shear action by a portion of the beam called the 'active link'. The active link provides a superior energy dissipation capability through its inelastic action. The EBF must, then, be designed so that plastic action of the active link occurs on overloading of the structure.
