2. A tension member has a span of 9 m and carries a tensile load of 981 kN. The member is to have two lines of rivets in each flange for the 20 mm rivets with standard diameter of 21 mm hole dimension with at least 3 rivets in a line. Use a 36 W section. Neglect the weight of member Fy = 248 MPa, Fu = 400 MPa. Possible Sections: W 250 x 60 W 250 x 54 W 250 x 67 A = 7613 mm² d = 2985 A = 6839 mm² A = 8516 mm? d = 306 d = 301.50 ry = 49.3 mm ry = 39.4 mm ry = 49.3 mm tf = 13.10 mm tf = 13.72 mm tf = 14.63 mm bf = 203.2 mm bf = 166.75 mm bf = 204.27 mm
