Intent

Intent 1:

To limit the probability that the overstrength related force modification factor used will not be appropriate for the ductility related force modification factor, which will not reflect that the product RdRo is a property of the Seismic Force Resisting System, which could lead to:

  • the excessive deformation of, or excessive stress in, the structural elements, which could lead to damage to the building, or
  • the excessive deformation of, or excessive stress in, the building structure, which could lead to damage to the building, which could impede the intended use and occupancy of the building.
