4.1.8.11.(10)

Intent 1:

To limit the probability that the calculation of loads due to earthquake will not take into account the forces due to the expected seismic torsional moment at any level of the building, taking into account the dynamic response of the building to maximum expected seismic ground motions, 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 direct Code users to Article 4.1.8.12. for the Dynamic Analysis Procedure.
