To limit the probability that the calculation of wind effects on the building structure will not take into account how the properties of the building structure affect dynamic amplification, which could lead to the excessive deformation of, or excessive stress in, structural elements, which could lead to damage to the building.
To limit the probability of the implementation of unacceptable design methodologies for the calculation of dynamic amplification due to wind, which could lead to the excessive deformation of, or excessive stress in, structural elements, which could lead to damage to the building.
