How to modell a plane and space truss? In STAAD just specifying Truss will do, but in SAP members are showing bending and even shears. Please help.

Hate to say it, but I think you have to select all of your frame elements and release the moments as appropriate at both ends.

In V7.5, even the truss templates are actually frames.

Remember that a truss is a simplification of an actual structure invented long ago in order to simplify structural calculations. Given the power of modern calculating tools there is really little need to stick with the old zero-moment-nodes model.
