Paper Title:
Numerical Simulation of Cold-Formed Steel Stiffened Lipped Channel Columns with and without Perforations
  Abstract

A nonlinear finite element model of fixed ended cold-formed steel stiffened lipped channel short columns with and without perforations was developed and verified against experiment results. Material and geometrical non-linearities were included in the finite element model. It was proved by comparison analysis that using weighted average tensile yield stresses of the flat and corner areas and the mean geometrical imperfections along the length of the specimens was suitable for predicting the failure mode, ultimate load and load versus displacement curves of the channel short column. The results got by FEA coincided with the experimental results.
