Abstract This paper presents the results of a theoretical-numerical study laterally-restrained thin-walled steel rectangular hollow flange beams subjected to bending, shear and bending interaction. Finite element analyses were carried out by using ANSYS software, validated previous experimental tests. Furthermore, effect intermediate stiffeners was investigated, where improvement percentage in ...

The cold formed steel section are increasingly used as a structural elements in low rise buildings recent times, due to the advantages like economic production, easy transportation, labor cost and high strength weight ratio. In current work G+3 storied building frame is studied for seismic wind load using Staad-pro software. Light gauge taken beam slab elements. analysis carried out by Equivale...
