3. Check that the secondary girder to primary girder connection by means of angles shown in the figure below is adequate. All dimnesions required are provided in the figure Q3. 155 90 50 40 W I9 800 900 . 8 @ 60 t = 15 40 Figure Q3 18.5 I 35 300 Main girder: S355JR, fy = 350 N/mm Secondary girder: S355JR, fy = 350 N/mm Angles: 2L 90 X 9, S355JR, fy = 350 N/mm Bolts: Diameter = 22mm; Grade 8.8 fyb = 640 N/mm, fub = 800N/mm? Bolt area at the bottom of thread: As = 303mm? Applied load: shear force V = 890kN (at the center line of the web of the main girder) 3.
