Why is the value of period very big?

Post by ashf »

Hi,
I have a 2D eccentrically braced frame,when I remove all springs,the period is big (2828900s).when I have springs and their nodes and equalDOFs,I see this error
WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 1
and period is 960.32 s.
Where is my problem?

Thank you
