Revision of Engesser’s Approach to the Problem of Euler Stability for Built-Up Columns with Batten Plates

摘要: Solving the buckling problem for a battened column as statically indeterminate structure yields Euler critical load that is significantly higher than being obtained on basis of Engesser’s assumption. The stability reduced to numerically solving two-point boundary value system recurrence relations between deformation parameters adjacent joint cross sections column. expression each further section linear function preceding possible using initial-value method. For columns with any degree static indeterminacy, force determined smallest eigenvalue fourth-order homogeneous algebraic equations. A computer realization present method requires implementing reorthogonalization vectors particular solutions relations. Plots number panels can be constructed batten rigidity parameter. Applying these plots useful in selecting designed.
