Difference between Fixed End and Pinned End in Structural Analysis using STAAD Pro

When conducting a structural analysis using STAAD Pro, it is important to understand the difference between fixed end and pinned end conditions.

Fixed end conditions in STAAD Pro are characterized by constraints that do not allow any displacement or rotation at the end of a structural member. This means that the fixed end is fully restrained and cannot move or rotate under load.

On the other hand, pinned end conditions in STAAD Pro allow rotation at the end of a structural member but do not allow any displacement. This means that the pinned end can rotate freely but cannot move laterally.

Understanding the difference between fixed end and pinned end conditions is essential for accurately modeling and analyzing the behavior of a structure in STAAD Pro.
