Somewhat related to the discussion of submittals of calculations: IBC 2000,
Section 1603 lists a number of design loads and related items which must be
shown on the construction documents. For earthquake design data, the "design
base shear" is required to be shown "regardless of whether seismic loads
govern the lateral design of the building".
Isn't this a bit of overkill for low seismic regions? In some areas, it can
be shown that wind load will govern over seismic loads with a brief
comparison of loads but without a detailed analysis of seismic base shear.
This requirement forces the engineer to perform more detailed seismic design
loads even when they do not govern design. Is this really a practical
