Hello everyone!
I am struggling to understand how "loadconst" works. For a static pushover analysis, it is clear to me that you need to set
loadConst -time 0.0
after the application of the gravity loads in order to keep the gravity loads constant during the application of the lateral displacements.
However, I have a different situation. I am trying to model a cyclic loading experiment in which load control and displacement control protocols are alternated. I apply a displacement, after that a force, after that another displacement and so on.
Do I need to apply "loadConst" in any instance of the code in this case? The force never remains constant during the test, but I am afraid I am missing something here, because the results are very far from the experiment. Any help?
How to set "loadconst" for my loading protocol?
