TLDR
In this paper, the authors investigate the flexural behavior, including the ultimate moment capacities and failure modes, of built-up cold-formed steel members with circular web holes and show that when the hole diameter-to-web depth ratio (d h/h w ) is 0.5, the influence of the holes on the moment capacities of beams is very small, however this is not the case when d h / h w further increases up to 0.7.About:

Experimental investigation and a novel direct strength method for cold-formed built-up I-section columns
TL;DR: In this article, the structural response and prediction of the ultimate strength of the cold-formed built-up I-section columns affected by local, distortional, global and in particular by the local-distortional (LD) interactive and local distortional-global (LDG) interactive buckling modes were investigated.

Flexural capacity of gapped built-up cold-formed steel channel sections including web stiffeners
TL;DR: In this article, the flexural capacity of back-to-back gapped built-up cold-formed steel (CFS) channel sections under four-point bending has been investigated, and it is shown that design in accordance with the AISI and Australia/New-Zealand standards, AS/NZS (2018) can be conservative by as much as 27%.

Design of Cold-formed Steel Built-up Sections with Web Perforations subjected to Bending
Liping Wang,Ben Young +1 more
TL;DR: In this article, a finite element analysis was performed on a wide range of cold-formed steel built-up section beams with different sizes of perforations under four-point bending and the critical elastic local and distortional buckling moments including the influence of holes that are required in DSM calculation were determined by rational finite strip analysis.

Investigation on flexural strength of cold-formed thin-walled steel beams with built-up box section
TL;DR: In this paper, the in-plane behavior of built-up box beams with nested C section and U section under pure bending about strong and weak axis is investigated, and the reasonability of the capacity superposition method and equivalent method is assessed by the discussion on test results and numerical analysis results.

Design of Cold-Formed Steel Built-Up Closed Sections with Intermediate Stiffeners
Ben Young,Ju Chen,Ju Chen +2 more
TL;DR: In this article, a series of column tests on cold-formed steel built-up closed sections with intermediate stiffeners is presented, where the test specimens were first brake pressed from structural steel sheets to form open sections with inter-web stiffeners, then two of the open sections were connected at their flanges using self-tapping screws to form the built up closed sections.
