Understanding the Difference Between Fixed Support and Pinned Support in STAAD Pro

In STAAD Pro, the difference between a fixed support and a pinned support lies in their respective degrees of freedom and constraints. A fixed support restricts translation and rotation in all three directions, providing full constraint to the structure. On the other hand, a pinned support allows translation in all directions but restricts rotation, providing partial constraint to the structure.

When modeling a structure in STAAD Pro, it is essential to properly define the type of support at each connection point to accurately simulate the behavior of the structure under different loading conditions.

By understanding the distinction between fixed and pinned supports in STAAD Pro, engineers can ensure the structural analysis results are robust and reliable for design considerations.
