Crippling Load Formula:
Definition: This calculator determines the crippling load for a column considering the factor of safety and Euler's buckling load.
Purpose: It helps structural engineers determine the maximum load a column can bear before buckling occurs, with a safety factor.
The calculator uses the formula:
Where:
Explanation: The formula adjusts Euler's buckling load by the factor of safety to determine the safe working load.
Details: Accurate calculation prevents structural failure by ensuring columns are designed to withstand loads well below their buckling threshold.
Tips: Enter the factor of safety (%), Euler load (N), and tolerance (±%). All values must be > 0 (except tolerance which can be 0).
Q1: What is a typical factor of safety for columns?
A: Common factors range from 1.5% to 3%, depending on material and application.
Q2: How is Euler's load determined?
A: Euler's load depends on column material, length, cross-section, and end conditions.
Q3: What does the tolerance represent?
A: Tolerance accounts for material variations and construction imperfections (±5% is common).
Q4: When would I use a higher factor of safety?
A: For critical structures, dynamic loads, or when material properties are uncertain.
Q5: Does this consider all failure modes?
A: No, this only addresses buckling. Material strength must also be checked separately.
