Nonlinear Buckling

The nonlinear Buckling load is determined for a multiple segmented member with various nodal boundary conditions. Intended for preliminary sizing and sensitivity analysis; validate independently for safety-critical use.

Model summary

Inputs: Number of segments and their section properties. Nodal boundary conditions including lateral and torsional springs.

Inputs: Nodal boundary conditions including lateral and torsional springs.

Outputs: Euler buckling load and nonlinear load.

Helpful hint 1: The nodes and segments are clickable for easy changes.

Helpful hint 2: The configuration and results can be saved to a JSON file for future use.

Use case: quick what-ifs, sensitivity, and early sizing—not detailed FEA.
