Compared to hot-rolled steel structures, cold-formed steel structures are susceptible to extreme winds because of the light weight of the building and its components. Many modern cold-formed steel structures have sustained significant structural damage ranging from loss of cladding to complete collapse in recent cyclones. This article first provides some real damage cases for light steel struct...

Small-scale, instructional shake tables, such as the UCIST shake table, are used at many colleges and universities to provide educational and research experiences in seismic behavior of structural systems. This paper describes the development of a physical model and associated educational materials that demonstrate the seismic behavior of shear walls used in cold-formed steel (CFS) building sys...

The thorough test programme and numerical simulation were conducted to examine the buckling behaviour loading capacity of cold-formed steel (CFS) built-up section members subjected axial compression. In programme, folded-flange channels grades G500 G550 designed assemble novel compressive members. Two types sectional profiles formed by composing with self-tapping screws. A total twenty-two spec...

This study proposes a design equation for built-up cold-formed steel (CFS) columns to eliminate the inconsistencies present in Section I1.2 of AISI S100 specification. The proposed was developed by using results from authors' compound spline finite strip-based numerical framework and 228 experimental literature on CFS columns, failing minor axis buckling. Investigations were conducted models wi...

This paper investigates the interior-one-flange web crippling strength of cold-formed steel channels at elevated temperatures. The stress-strain curves G250 and G450 grade (CFS) ambient temperatures were taken from literature varied 20 to 700 °C. A detailed parametric analysis comprising 3474 validated finite element models was undertaken investigate effects holes bearing length on behavior the...

C and Z sections are two of the most common cold-formed steel shapes in use today. Accurate prediction of the bending performance of these sections is important for reliable and efficient cold-formed steel structures. Recent analytical work has highlighted discontinuities and inconsistencies in the American Iron and Steel Institute ~AISI! and Canadian Standards Association ~S136! design provisi...

Light-gauge steel-framed (LSF) walls are being adopted by the Algerian construction industry as a new alternative to traditional infilled frames due advantages they provide. The strength-to-weight ratio of Cold Formed Section (CFS) leads lighter structures and decrease in building cost. However, case fire, high shape factor combined with loss material properties unprotected, slender CFS can res...
