4.1.8.18.(6)

Intent 1:

To limit the probability that the inertial seismic force applied by a tank containing liquid or by a flexible or flexibly connected piece of machinery, fixture or equipment to the building structure will not be taken into account in the structural design, which could lead to structural failure due to the dynamic response of the tank or piece of machinery, fixture or equipment when it is subjected to the maximum expected seismic building 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.
