Design of cold-formed steel battened built-up columns
CFS battened built-up sections have several benefits, but these advantages are rarely addressed in the current design formulas [7-9]. Battened built-up sections are not explicitly addressed in the EN [9], although it provides a global buckling curve for calculating the buckling resistance of a select few individual and built-up sections.

Theory of Built-up Sections – Civil Engineering Projects
A built-up beam is also known as compound beam. The built-up beams are used when the span, load and corresponding bending moment are of such magnitudes that rolled steel beam section becomes inadequate to provide required section modulus. Built-up beams are also used when rolled steel beams are inadequate for limited depth.

Shear Flow & Built-Up Sections – The StructEd
Built-Up Sections. Any section made by combining two or more components is known as a built-up section, since it is built up out of various other components. These components are often rectangular shapes because materials like steel and wood can be had readily in large sheet/plate format, which works well with building large or custom beam shapes.
