Abaqus load steps

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

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.
