Flexibility in the manufacturing of cold-formed steel (CFS) cross-sectional shapes provides a unique opportunity to improve load-carrying capacity these elements, leading more efficient and economic structural systems. This paper presents practical constrained optimization methodology for pin-ended anti-symmetric CFS beam-columns members with different lengths subjected various combinations axi...

in this study, the effects cold rolling and annealing parameters during thermomechanical processing of the aisi 201ln stainless steel were investigated. the cast samples were homogenized, hot-rolled and solution-annealed to acquire a suitable microstructure for the subsequent thermomechanical treatment. unidirectional and transverse multi-pass cold rolling at 25, 0 and -15 °c was carried out to...

This article presents a procedure for the reliability assessment of cold-formed steel beams based on Direct Strength Method (DSM) and Effective Section (ESM). Using comprehensive database, statistical analysis test results was performed to determine properties professional factor random variable. The parameters related material strength, geometric load effects were obtained from established ref...

Timber panels and cold-formed steel sheeting are widely used in the construction industry, especially prefabricated structures, temporary housing informal settlements. This is because these materials available, can be cut fixed with hand tools, their lightweight makes them easy to transport build with. When together, there a potential for composite action developing between timber underlying sh...
