5.32.11 Repeat Load Specification
Purpose
This command is used to create a primary load case using
combinations of previously defined primary load cases.

This command can be continued to additional lines by ending all
but last with a hyphen. Limit of 550 prior cases may be factored.
Prior cases to be factored may also contain the REPEAT LOAD
command.
Description
This command may be used to create a primary load case using
combinations of previously defined primary load case(s). The
REPEAT load differs from the load COMBINATION command
(Section 5.35) in two ways:
1) A REPEAT LOAD is treated as a new primary load. Therefore,
a P-Delta analysis will reflect correct secondary effects.
(LOAD COMBINATIONS, on the other hand, algebraically
combine the results such as displacements, member forces,
reactions and stresses of previously defined primary load cases
which were evaluated independently).
2) In addition to previously defined primary loads, the user can
also add new loading conditions within a load case in which
