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.

Connection type Performance criteria R(Response Modification Coefficient)
OMF (Ordinary Moment Frame) Frame to accommodate minimum inelastic behaviour 3.5
IMF (Intermediate Moment Frame) At least 80% of the full plastic moment of the beam at 2% of the drift angle 4.5
SMF (Special Moment Frame) At least 80% of the full plastic moment of the beam at 4% of the drift angle 8

 


Characteristics

  • Structure : SMF system (Development of SMF up to 1500mm in height of the world’s largest beam)
  • Economics : Maximum section (749 species 􂏚10% reduction in structural member)
  • Eco-friendly : Long life by safe seismic system (reduction in carbon emissions)
  • Quality : Strictness (fabrication tolerances)
  • Design : Convenience (MIDAS Gen)
  • Period : Quick (35 days in Korea, 115 days in the U.S)
