STAAD.Pro - External load combination file

Is it possible to define all of your load combinations in an external text file and have STAAD read that file?  I have a model w/ +10k load combinations and opening/saving/editing the file is too time consuming.

  • Dynamics,

    Glad you found it helpful.

    Ludwigev,

    For creating combinations containing load cases created by the moving load generator, here is a way. It involves the feature called "Predefined  Load to be Added" and is available at the same location in the GUI where you specify the number of cases to be generated from the moving vehicle.

     If you prefer the STAAD editor method, the command is called "ADD LOAD i" and is described in section 5.32.12 of the Technical Reference manual.

    Let's say we want to add dead load (load case 1) and imposed load (load case 2) to the generated moving load cases. First, create a REPEAT LOAD  (load case 3) which combines cases 1 and 2.

    LOAD 1 DEAD LOAD

    SELFWEIGHT Y -1

    LOAD 2 IMPOSED LOAD

    MEMBER LOAD

    1 TO 6 12 TO 17 23 TO 28 34 TO 39 45 TO 50 UNI GY -1

    LOAD 3 DEAD + IMPOSED

    REPEAT LOAD

    1 1.0 2 1.0

    Next, load 3 has to be added to each case generated from the moving load. So, in the GUI, the "Predefined Load to be Added" would be case 3. Or, in the editor, add the words, "ADD LOAD 3" to the LOAD GENERATION command.

    LOAD GENERATION 10 ADD LOAD 3

    TYPE 1 7.5 0 0 ZINC 10

    The result is that each generated load case will be a combination of the moving load and the static loads.



  • That is the way I would normally do it, but I have multiple moving loads in the same combination.
