The cross section of Grade 350, 6 m long, welded plate girder is shown Figure Q2. (a) Check the limiting web thickness and section classification for this cross section. (5 marks) (b) Check the shear buckling capacity for the unstiffened web. (10 Marks) (c) For a factored ultimate limit state (ULS) shear force, V=750 kN, find the shear stiffener spacing to avoid web shear buckling (20 marks) (d) Check the pairs of web stiffeners 8 mm thick with an outstand of 90 mm against the minimum A, and I, values. (10 marks) (e) For a reaction force of V= 750 kN, check the adequacy of a 200 mm x 10 mm bearing stiffener against web crushing if the stiff bearing length is 200 mm. (5 marks) 320mm 20mm Stiffener pair 840 mm x 90 mm x 8 mm thick 880 mm 6mm 20mm Figure Q2: Cross Section of Welded Plate Girder
