I have a question regarding IBC Equation 5-2..
Where the code define "Sa", It said " the actual number of stories above grade plane, not to exceed 3".
What does it really mean? What if I have an occupancy B, Type II A, sprinkled building, which has an allowable number of 6. Can the "Sa" in this equation has to not exceed 3? Does that mean I can only have a max. 3 stories building, if i want to benefit from the frontage area increase.
