Strand7 Software:  Galleries:  Structural:  I-beam


Plate/shell model of an I-beam. One symmetric half has been modelled. The plate elements are rendered as solids to clearly present the relative thickness of flange and web.

The first buckling mode for the beam is a local flange and web mode.

The linear stress distribution, due to a concentrated force, just before the beam yields.

The section is now extensively yielded.

Upon unloading, residual stresses remain in the beam.
