Attic truss analysis

[acsavo]

I am currently analysing an attic truss rafter as a single 2-D frame frist in SAP2000 step 2 is to replicate as a roof structure. my problem lies with applying end releases to the members. When i release major; minor moments and torsion to simulate a pin the frame fails the sap analysis. What am i doing wrong

You have to adjust the DOFs in the Analysis-Options according to the releases made to your joints.
