Boundary conditions for buckling of column

Click For Summary
SUMMARY

The discussion centers on the boundary conditions for buckling of columns, specifically fixed-fixed and simply supported cases. For fixed-fixed boundary conditions, both x and y displacements must be restrained, while for simply supported conditions, only y displacement is restrained. Participants express confusion regarding the simultaneous application of loads to fixed ends and how this affects displacement, highlighting the need for clarity in defining boundary conditions during analysis.

PREREQUISITES
  • Understanding of column buckling theory
  • Familiarity with boundary conditions in structural analysis
  • Knowledge of displacement constraints in engineering mechanics
  • Experience with load application methods in structural simulations
NEXT STEPS
  • Research fixed-fixed boundary conditions in structural mechanics
  • Study the effects of displacement constraints on buckling behavior
  • Explore load application techniques in finite element analysis (FEA)
  • Learn about simply supported column behavior and its applications
USEFUL FOR

Structural engineers, mechanical engineers, and students studying buckling phenomena in columns will benefit from this discussion, particularly those involved in analyzing and designing structural elements under various loading conditions.

For fixed-fixed BC's, i have to arrest x and y displ. For simply supported case, i have to arrest y displ. Then my doubt is, while applying force at the end of the column, how the displacement will happen for fixed-fixed column.

You want to fix both ends and then apply loads to them?
 
yeah...that's my doubt...
 
I don't see how you want to call the ends fixed and apply loads to them simulateously. Are you sure that is what is being asked of you?

I read it as one end being fixed in both x and y, and the other only in y, thus free to move so as to allow buckling, like http://upload.wikimedia.org/wikipedia/commons/5/54/Buckled_column.png" Is that the problem you're describing, karthickaero1?

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
