The analysis terminates when the reaction force at the footing reaches zero. Does this indicate that the footing has undergone uplift (loss of contact) failure?
If so, is there a way in SeismoStruct to continue the analysis beyond this point (for example, by allowing partial contact, gap opening, or re-contact behavior), rather than stopping the analysis altogether?
I have attached a screenshot and the corresponding .spf file for reference.

Re: ssilink1 uplift failure
Yes this probably means uplift of the footing, after which the program is unable to find numerical convergence. There is no automatic way to prevent this in SeismoStruct. You need to check out the details of the footing and the analysis (probably with the help of your supervisor).
