Assigning global/local end displacement to a member in SAP2000?
Assigning global/local end displacement to a member in SAP2000?
(OP)
Hi,
I am trying to get axial force on a specific member with known end displacements of a 2D truss. However, although I assigned the displacements to joints, after 'run', I get literally nothing,I mean no forces no displacements at all. Is there anyway to assign kinematic degree of freedoms in SAP2000 ?
Thank you so much.

Maybe the structure is statically determined ? it means that an imposed displacement doesn't cause internal forces.

Imposed displacements only work on restrained degrees of freedom.

Yes I also forgot to mention what darkjmf1 said. Imposed displacements only work on restrained degrees of freedom.
