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.
 
Look in the Abaqus documentation keywords manual.

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.
