چکیده مقاله :
The aim of the present study is to examine the behaviour of cold-formed steel (CFS) lipped channel built-up I-section withedge and intermediate web stiffeners under bending. Initially, the section dimension of length, width of the flange and depth ofthe sections are optimized numerically and finally, it is validated with the test results. All the select cross-section dimensionshave satisfied the pre-qualified beam dimensions. Numerical analysis is carried out using the software ABAQUS. Totally,four section geometries are tested experimentally. After validation, a total of 75 parametric studies are carried out using theverified finite element model. All the results are compared with the direct strength method specifications for CFS structuresand the suitable design modifications are detailed.
