Abstract Currently, corrugated cold-formed steel sheets are widely used as parts of cladding panels and roof envelopes in public residential buildings. However, the design is weakly covered by current building codes. This paper investigates load-bearing capacity with sinusoidal profile, presenting results experimental research that was performed GRISPE project at Research Center for Steel, Timb...

This paper presents the results of a study aiming at shape optimising singly-symmetric cold-formed steel purlins. The “self-shape” optimisation algorithm previously developed, proven to be robust and converge known solutions is used for this purpose. Eight cases are considered, consisting 1.5 mm 1.9 thick purlins, spanning either 3000 or 8000 drawn with 4, 6 8 elements per half cross-section. a...

The modular construction industry often seeks cost-effective, high-performing, and longer-span members in buildings to ensure efficiency quality. Accordingly, the idea of built-up sections was brought into gain numerous benefits including higher structural capacity, improved torsional rigidity, increased stiffness. While limited research studies have been carried out study performances sections...
