| Abstract |
An innovational method for solving the Euler–Bernoulli problem of an overall buckling of
the uniform column supported by rotational springs of stiffnesses γ1, γ2, N·m free from traditional simplifications (invariable flexural stiffness and length) is given. It is based on a natural and comprehensive constraint on the restored axis length. A system of algebraic equations relating the critical stress σcr to the nonlinear compression diagram ε(σ) of the material, the slenderness of the column λ and the values γ1, γ2 has been obtained, solved and verified in important special cases. It is shown that columns of the same material with the same so-called the reduced spring stiffnesses have identical dependencies σcr(λ). It is shown that columns with λ≤λmin(γ1, γ2) cannot be buckled by any axial load F for various types of ε(σ) (Ramberg-Osgood, rational fraction, polynomial, etc.). |
