Cold-formed steel sections are becoming popular for different structures, because they have a high resistance against straining actions, with minimal weight compared hard sections. Recently, perforated cold-formed (PCFS) been used in many applications, such as upright storage racks. Experimental research into the behavior of rack uprights subjected to axial compression is presented this paper. ...

Lateral Distortional Buckling (LDB) is a mode of instability in Steel-Concrete Composite (SCC) beams that yet to be fully understood by the structural engineering research and design community. This work investigated numerical methods understand LDB behavior SCC under negative moments exhibit nonlinear behavior. Focus study was develop validate 3-Dimensional finite element (FE) models which cap...

The lateral-torsional buckling (LTB) strength of cellular steel girders that were subjected to web distortion was rarely examined. Since no formulation has been presented for predicting the capacity of such beams, in the current paper an extensive numerical investigation containing 660 specimens was modeled using finite element analysis (FEA) to consider the ultimate lateral-distortional buckli...

The object of this study is a structural member made from C-shaped cold-formed profile, investigated to search for optimal cross-sectional dimensions. parametric optimization task stated as the problem find dimensions under axial compression conditions, taking into account its post-buckling behavior (local buckling web and flanges, well distortional cross-section) requirements. In case, materia...

Parametric optimization problem of cross-sectional sizes for cold-formed C-profiles subjected to central compression has been considered by the paper. formulated as follow: define optimum taking into account post-buckling behavior and structural requirements when stripe width thickness well type profile are constant defined designer.
 Criterion load-bearing capacity maximization assumed pu...
