Bending performance of cold formed steel structural member with perforated section in housing framing system

Abstract

The study shows a numerical analysis on bending behavior of cold-formed steel framing system and the effective cost reduction between perforated and non-perforated steel section in steel framing system. The results are presented in the form of displacement and yield moment. Using finite element analysis software, a total of 26 set of nonlinear analysis were executed to determine the effects of opening spacing, edge distance and thickness of section on bending behavior. The result shows that the increasing of the opening spacing and edge distance would increase the bending capacity. C-channel steel section showed better moment resistance in thicker section. The result was then compared to the C-channel steel section without perforation. From the analysis, it was observed that C-channel steel section without perforation had higher bending capacity than C-channel steel section with perforation in major axis. However, there is a small difference in terms of yield moment when comparing C- channel section with 0.4D of square opening and 0.3L edge opening as well as 0.1L opening space with C-channel section without perforation while reducing the volumes up to 7.28%. Thus, C-channel section with 0.4D of square opening, 0.3L edge opening and 0.1L opening space give a very effective cost reduction.

Buckling capacity of cold-formed steel structure column member with perforation section in affordable house framing system

“…In terms of yield moment, small differences is observed when comparing C-channel section with 0.4 D of square opening and 0.3 L edge opening as well as 0.1 L opening with C-channel section without perforation while reducing the volumes up to 7.28% (De’nan and Sheng, 2020). The 200-mm reinforcement type is used to strengthening open CFS sections under flexural loading (Taheri et al , 2020).…”
