In this study, an innovative fabricated angle bracket connection for joining cold-formed steel structures is presented and investigated. The innovation lies in the especially designed manufactured method of connecting C-profile using clinch pressing. This novel can be used to connect elements such as beam trusses at ends chords or anchoring column base. Five specimens were experimentally tested...

This paper presents the results of finite-element simulations leading to development a design method using direct strength (DSM) for transversely loaded thin-walled steel beams prone local and distortional buckling failures at elevated temperatures. The systematic extensive numerical parametric study covers different dimensions sections, temperature distributions in cross-section, grades load r...

Abstract The optimisation of the cross sectional geometry cold-formed steel sections has been subject numerous past studies. These walls consist intermittently placed studs, lined most commonly with gypsum plasterboards. Experimental evidence shown that restraints provided by wall sheathing can have a significant impact on axial compression capacity these studs. However, studies incorporating i...

Cold-formed sections (CFS) fabricated using high strength steel have recently been utilised in construction due to their numerous advantages, such as higher load-to-weight ratio, flexibility of shape, and availability relatively long spans. High CFS channel can be used purlins joists structural systems; thus, they are vulnerable different buckling instabilities, including web crippling. Predict...

In current design standards, cold-formed steel (CFS) beam-column elements are generally designed by considering fully warping free behaviour in their supports, which means the benefit of warping-restrained boundary conditions is neglected. addition, while a non-linear relationship governs interaction axial compression and bending, simplified linear expressions prescribed may lead to unreliable ...

Cold-formed thin-walled steel has light weight, large width thickness ratio, good economy and seismic performance. It is easy to realize standardization of design, very suitable for the development prefabricated buildings. Due ratio cold-formed , plate prone local buckling when it compressed, which will reduce ductility bearing capacity structure, also leads limitation use structure system in m...
