Special Moment Frame using Pos-H

POSCO – All Regions

Special Moment Frame have seismic performance at least 80% of the full plastic moment of the beam at 4% of the story drift angle. SMF are expected to withstand significant inelastic deformation during earthquake and can be designed by reducing the amount of frame by up to 30% by applying the Response modification coefficient R value 8.
