Abstract:
Based on the concept that the axial load could be equivalent to a negative stiffness, the stability problem of cantilever column was solved by converting the column middle load to a column top load and a practical formula was suggested. Generalizing the calculation formulas to the stability problem of cantilever column with multiple-varying axial force, a more universal practical formula was built and was validated by finite element software. The result shows that the formula is safer than the exact solution and is precise in a certain level, so it can be used for engineering design and theoretical calculations.
