Behaviour and Design of Lean Duplex Stainless Steel (LDSS) Beams with Web Openings Under Pure Bending
The flexural behaviour of lean duplex stainless steel tubular beams with web openings is presented. A finite element study is carried out on lean duplex stainless steel sections with web openings to determine the effects of the perforations on the bending capacity, deformed shapes and local buckling characteristics. The study also aims in particular for a comparison between sections having circular or extended openings with a wide range of section slenderness. The bending capacities from the finite element results are also compared with the American specification, European specification along with direct strength method. Both ASCE and EN can give a good prediction of the design strengths, however, the direct strength method showed unconservative predictions. Modifications have been proposed to both the ASCE specification and the direct strength method for LDSS sections with web openings.
