OS2 Structural Safety



Intent 1:

To limit the probability that the calculation of the equivalent static base shear will not take into account the participation of higher modes in the dynamic response of the structure by the inclusion of the factor Mv, which could lead to structural failure, which could lead to harm to persons.

Intent 2:

To modify the calculation for the overturning moment at the base of the structure, on the basis that the higher modes included in the base shear do not contribute significantly to the base overturning moment.
