Dear Engineers,
Is it possible to create +Fy restraint support in STAAD?
When I use
FIXED BUT FX FZ MX MY MZ
It restraint in both +Fy and -Fy
My condition is simple rest support. Only +Fy restraint and -Fy is free
Is it possible to create such a support in STAAD?
Yes, It is possible to create +Fy restrain Support in Staad.Pro.
You can assign this kind of support (+Fy restrain Support) as a Compression Only Spring.
I have attached a sample where I have assigned a Compression Only Spring at node 1. So the support at that node will remain only when the reaction is +ve and will deactivated for (–ve) negative reactions.
Hope this helps you.

So in case of a wall retaining soil how will I specify the direction of the compression only spring for the wall element?
You will need to assign compression only or tension only support in an appropriate global direction. Some more details can be found here: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/12687/tensioncompression-only-spring-support
