Numerical Optimization of Cold Formed Closed Built-up Steel Column

Pradeep T, Arun N

The Optimization of cold formed closed steel built-up columns without stiffeners is performed using finite element analysis. An accurate finite element model is used for study in which different size of webs are investigated. The closed cold formed built-up steel column strength were studied with and without coupling of section. The finial section of column buckling behaviour is predicted by the nonlinear finite element method anddiscusses the unfactored design column strength
