Zero Stiffness Warning
Zero Stiffness Warning
(OP)
Hi!!!!
I'm getting a warning in Staad Pro saying something like Zero stiffness..
What's the best way to get rid of it???
Any suggestions...

It's working fine!!!
But why is that error arising??
What is the logic behind using that SET PRINT 1???
It'd be much helpful if u could furnish the reason for that...

RE: Zero Stiffness Warning
It is not an error. It is rather more a note or FYI. Zero rows and zero columns (at a joint) in the global stiffness matrix can occur when trusses or releases or tension/compression-only are used by some or all of the members at a joint. The zeroes are almost always harmless but the message is printed in case the engineer is not expecting zeroes. It is possible that a wind load/floor load will generate a load at a zero dof and in effect be lost but that is rare. The Print Static Check will be out of balance in such a case.
