Abstract
Abstract: The paper deals with the shear behavior of the Lean duplex stainless steel perforated hollow beams. Lean duplex stainless steel offers significant advantages such as better economy, improved strength, high temperature properties, acceptable, weldability and fracture toughness properties. Hollow beams have wide range of applications in the construction industry, such as in buildings, bridges, oil refineries etc. The ultimate strength and elastic stiffness of a structural member can vary with perforation position, size, shape, and orientation. In this study the shear behaviour of perforated hollow beam is studied based on different shapes of perforation. . Different shapes of perforation mainly include circle, square and diamond. ANSYS Workbench is used to analyze the shear behavior of perforated lean duplex stainless steel rectangular hollow beams.
