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 ends: | K=0.5 | K=0.65 |

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.
