Sentence 4.1.8.4.(5)

Intent 1:

To limit the probability that the calculation of effects due to earthquake will not take into account the properties of the site response, 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.

Intent 2:

To clarify how intermediate values of the acceleration- and velocity-based site coefficients, F_a and F_v, are to be determined.
