analysis not complete

[Ahil_Anand]

I have three simple models and I want to run a pushover analysis for them:

1- A simple beam should be push in vertical direction until the obvious shear in 0.25 span of the the beam reach to a specified value (450 KN).
2- A simple cantilever column push in horizontal direction until the obvious shear in the column reach to a specified value (300 KN).
3- A two story RC structure push in horizontal direction until the obvious shear in the bottom column reach to a specified value (1360 KN).

The specified considered values determined based on experimental values. Therefore, the considered elements should be reach to them. My problem related to the analysis which was not completed and have error message and not reach to the considered values. The capacity criteria which were determine as default by the program, showed that the elements reach to fraction in steel!! and crush in concrete!! in the analysis, and based these, the analysis doesn't complete. Please help me to solve the above problem. The attachments are the files:

Dear Ahil_Anand,

Could you please check if your model corresponds to the experiments you refer? For example the materials' strength or the elements connectivity, the restraints and constraints etc.

If you are sure that your models are correct, could you send me the *.spf files at z.gronti@seismosoft.com in order to take a look?

It sent to your email. Thank you very much for your answer.

Dear Ahil_Anand,

I took a quick look at your models. All three models reach their capacity during the analyses. The analyses stop because the structures cannot sustain the additional deformations.
I think that you push them too much. Perhaps you should assign a smaller value for the target displacement.
