OS2 Structural Safety

Intent

Intent 1:

To limit the probability that the structure will not be designed for overturning moments, which could lead to structural failure, which could lead to harm to persons.

Intent 2:

To modify the calculation for the overturning moments because the higher modes that are included in the base shear do not contribute significantly to the overturning moments.
