5.31.2.6 IBC 2000/2003 Load Definition
Description
The specifications of the IBC 2000 and 2003 codes for seismic
analysis of a building using a static equivalent approach have been
implemented as described in this section. Depending on this
definition, equivalent lateral loads will be generated in horizontal
direction(s).

The seismic load generator can be used to generate lateral loads in
the X & Z directions for Y up or X & Y for Z up. Y up or Z up is
the vertical axis and the direction of gravity loads (See the SET Z
UP command). All vertical coordinates of the floors above the
base must be positive and the vertical axis must be perpendicular
to the floors.
The implementation details of the respective codes are as follows:
IBC 2000
On a broad basis, the rules described in section 1617.4 of the IBC
2000 code document have been implemented. These are described
in pages 359 thru 362 of that document. The specific section
numbers, those which are implemented, and those which are not
implemented, are as follows:
