Notional Loads on Load Combinations

  • Hi,
    I have to take into account the NOTIONAL LOADS into my Analysis so I need to include their effects in the Load Combinations, so the question is:

    Which is the correct way to state them?,
    1) As a Basic Load, and then called them from Load Combinations through REPEAT LOAD

    -------------------------------------
    LOAD 1 DEAD LOAD
    50 UNI GY -0.6
    LOAD 2 DEAD OPER
    50 UNI GY -0.4
    LOAD 3 NOTIONAL LOAD (+NLX)
    NOTIONAL LOAD
    1 X 0.005 2 X 0.005
    *
    LOAD 100 1.4(DEAD +NLX)
    REPEAT LOAD
    1 1.4 2 1.4 3 1.4
    -------------------------------------

    2) To include NOTIONAL LOAD command into the Load Combinations through REPEAT LOAD

    -------------------------------------
    LOAD 1 DEAD LOAD
    50 UNI GY -0.6
    LOAD 2 DEAD OPER
    50 UNI GY -0.4
    *
    LOAD 100 1.4(DEAD) +NLX
    REPEAT LOAD
    1 1.4 2 1.4
    NOTIONAL LOAD
    1 X 0.007 2 X 0.007
    -------------------------------------

    I'm asking because like two years ago the Option 1) & 2) used to provided not the same results, so after talking with a STAAD Technician we noticed that the correct way was the No. 2).. now, with improved versions of the software it would be changed; may someone confirm that?

    Thank you in advance.
