Regarding stiffness warning check

Dear Associates,

While checking the warning in staad model for  member stiffness as shown below :

*WARNING- ZERO STIFFNESS IN DIRECTION 3 AT JOINT    303 EQN.NO.    1789

          LOADS APPLIED OR DISTRIBUTED HERE FROM ELEMENTS WILL BE IGNORED.

          THIS MAY BE DUE TO ALL MEMBERS AT THIS JOINT BEING RELEASED OR

          EFFECTIVELY RELEASED IN THIS DIRECTION.

*WARNING- ZERO STIFFNESS IN DIRECTION 4 AT JOINT    303 EQN.NO.    1790

*WARNING- ZERO STIFFNESS IN DIRECTION 5 AT JOINT    303 EQN.NO.    1791

*WARNING- ZERO STIFFNESS IN DIRECTION 6 AT JOINT    303 EQN.NO.    1792

But at this joint , not even a single member is released .

But at this joint all members are defined as truss members .

So I didn’t get that how should I remove this warning ?

Thanks!

Abhijeet
