Pushover on materials with softening in Abaqus

hello dear friends,


I am trying to conduct a pushover analysis on a 2D dam model by abaqus.the material is concrete and is modeled by damage plasticity. the problem is because of the softening issue ,while I apply force, the solution would not converge with a low magnitude of load and it remains elastic so I can not obtain a complete pushover curve. I have very little time to get the results so I appreciate anyone who would help.

it is so simple.

the structure shoyld be subjected to lateral displacement instead of force.

define allowable displacement according to FEMA or ICOLD.

best regards
