error in model

[derogar]

Dear Silvia,



Thanks alot for reply. As you mentioned in the previouse email, I have corrected the mistakes in the attached files but when the cyclic loading is applied, it does the analysis only for 1 cycle ad after 1 cycle there are errors in the analysis as follows:

and I am sorry that I bother you by not sending the problem to the forum.



Thanks a lot.



Looking forward to hear from you very soon.

your demands on the section are too high.
have you looked at the overall response you are getting?
have you looked at the critical section?

Hi

I have tried many times to enter in order to aks some quetions, but i could'nt, also I made other registration, but I didn't solve the problem.
can you help me? What do I have to do?
How did you do in order to ask questions?
It's very important, because I'm doing my thesis with opensees.

Thanks
