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...

Angle sections are commonly designed to bear only axial force, usually neglecting the additional bending moments resulting from the eccentric connection and the shift of the effective centroid. The current work deals with the capacity of single-bolted equal angle sections made from cold-formed steel. The experimental investigation presented herein includes tension and compression tests that sub...

To study the cold-forming effect on yield strength distribution of cold-formed thick-walled steel, material tensile tests and axial compression were conducted steel-lipped channels. undertake tests, five types lipped channel sections with varied thicknesses nominal strengths selected. The test samples taken from web, flange, curled edge, corner sections, respectively. Next, a corresponding mode...
