Instability of a Space Arc Frame

Application ID: 19821

This model illustrates the instability of a space arc frame under concentrated vertical loading. The Beam interface is utilized.

Two different approaches are used:

  1. A full incremental nonlinear analysis, where a small lateral load is applied to break the symmetry of the structure
  2. A linear buckling study

The results are compared with available literature data.

This model example illustrates applications of this type that would nominally be built using the following products:
