|Java buckling calculation and plotting programme - Johnson and Euler criteria - for concentrically loaded columns.|
Enter the values in the units indicated in the top 7 boxes. For an end fixing factor enter a value from the table below.
|End Fixings||Theoretical K value||Practical K value|
|pinned frictionless ends:||K=1||K=1|
|fixed - pinned and guided:||K=0.7||K=0.8|
|fixed - free:||K=2||K=2.1|
Click on the 'Calculate' button.
For slender columns, with a slenderness ratio greater than the critical value, the Euler load is calculated and diplayed. For short and intermediate columns, the Johnson load is calculated and displayed.
