Nonlinear beam behaviour example
This shows the deflection and bending moment history of a propped cantilever loaded with a point load at mid-span. The beam has a plastic moment capacity of 100 kNm and a shape factor of 1.12. A strain hardening modulus of 2% of the modulus of elasticity is used.
The model is based on that given in Advanced Analysis and Design of Steel Frames by Li and Li, Wiley 2007.
