Sentence 4.1.8.3.(6)

Intent 1:

To limit the probability that stiff elements that are not considered part of the Seismic Force Resisting System will be subject to loads for which they were not designed, which could lead to:

• stiffening of the structure, which could lead to a change in the dynamic characteristics of the building structure (natural period and mode shapes), which could lead to an increase in the inertial forces in the building structure, and
• inadequate strength in the stiff elements.

This is to limit the probability of structural failure of the stiff elements and the Seismic Force Resisting System, which could lead to harm to persons.
