In recent years, cold formed steel sections are used more and more as primary framing components and as a secondary structural system. They are used as purlins and side rails or floor joist, and after that in the building envelops. Beams are not perfectly straight and are usually associated with geometric imperfections. Initial geometric imperfections can significantly influence the stability response...
The elastic shear buckling behavior of tapered plates with circular opening under shear stress has been studied numerically. Also, different aspect ratios and tapering ratios are studied numerically. Several values of circular opening diameters are considered in this study. In addition, tapered plates without openings are studied numerically for the different aspect ratios and tapering ratios to obtain...
