Why never is there a structure without equilibrium in Sap2000?
Why never is there a structure without equilibrium in Sap2000?
(OP)
Hi,
I have a dude with the way that Sap2000 analizes a structure that doesn´t have equilibrium.
If I modelize a simple beam with only restrains in one of both supports, the analisys does not return an error.
I attach a drawing with an example.
Thanks

"The structure is unstable or ill-conditioned". The analysis does run, but deflections will be very large. To see the last analysis results, go to analyze-->show last run results.

The deflection is 3,985E+12, so virtually infinite.
In Analiyze-> Show last run details:
* * * WARNING * * *
THE STRUCTURE IS UNESTABLE O ILL-CONDITIONED !!
It´s clear.
Thanks again
