Re: Modelling rigid links with STAAD III

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Generally speaking,
The slave joint is the joint that has the same deformation(s) as the master joint. In other words, if you have
(M) matster joint, and (S) slave joint, you can enforce joint (S) to have the same deformation(s) as joint (M). Consider a horizontal frame element strats with joint (20) and ends with joint (21) and now you want to ignore the axial deformation in this element, you can make joint 21 as a slave joint to joint 20 (the matster joint) in the X-Direction.
Hope this will help

Subject: Modelling rigid links with STAAD III

I am modelling a diaphragm with STAAD III. I always have the doubt about what is the master joint and what are the slave joints. I have read the manual many times and it is not clear.
