Linear and Non-Linear Buckling Analysis using FEA

  • Linear buckling analysis enables an assessment of the buckling resistance of a structure, and may be particularly useful for structures not falling within the scope of codes of practice.
  • In some instances, a linear buckling analysis may appropriate to satisfy checks against buckling. In others, it may only provide a good starting point for a thorough nonlinear buckling analysis.
  • Nonlinear buckling analysis provides a detailed buckling assessment and can include geometric, material and boundary effects.

Steps of Buckling Analysis
  • Linear Buckling analysis
  • Non-linear Buckling analysis
  • Erection analysis
  • Mesh sensitivity analysis

Buckling analysis of structures to codified requirements is often over-conservative. For existing fluid structures, assessment or load rating to regional design codes often shows they ‘fail’ buckling checks, but detailed buckling analysis with LUSAS can often reveal additional ‘hidden’ capacity.

For new plate girder, box or tub girder bridge designs, linear and nonlinear buckling analysis using LUSAS can investigate the girder stability during erection, look at the effects of a slab casting sequence, and also help to optimize the size of the web and flange plates, bracing, stiffeners and position of any temporary supports used
