AD.2007-07.2.14* Load Combination Enhancements

It is now possible to refer to a previously defined load combination within a new load combination. For example, a SRSS combination of individual response spectrum cases can now be referenced in a load combination along with dead load, live load, etc.

There are no changes to the input file syntax. Load combination definitions may now refer to existing load combination numbers along with load case numbers.

Note: There is no limit to the amount of load combination "nesting" which can be done in STAAD.Pro, other than the total limit of load cases and load combinations allowed by the program.
