Abaqus load steps
Abaqus load steps
(OP)
Hello,
I'm modeling a simple steel beam in Abaqus 6.7-1 for catenary action analysis. The beam is symmetrically loaded with 6 concentrated framed-in beam loads, it's own dead load, and a large midspan concentrated load. I'm using a RIKS analysis for only the midspan load. I broke the loadings into 6 different steps. The first step is dead load. Each of the next four steps is a quarter of the total framed-in beam loads. The final step is the midspan RIKs load. My question is, does abaqus add a previous load step to the following load step? If I eventually want all of the loads to be acting at once, do I have to put all of the loads in the final step, or will abaqus add all of the previous loads to the final load step? Thanks.

RE: Abaqus load steps
For *CLOAD, *DLOAD .... you have the optional parameter OP
With OP=MOD (which is the default) all existing CLOADs, DLOADs remain in force (either modified or additional ones added)
With OP=NEW all existing CLOADS, DLOADS are removed.
