Cover x Plate 6=350mm 22mm ,662/ WF section H.--NA la 22mm b=350mm Problem: Determin (with cover Plate) D unit Weight (W = k/m) that the Wf section Can Cary wherei L=9 maters givent weight of the beam (WP) = 658 N/m d=469.45mm Sx= 1188 x 103 mm bF= 178.79 Ix = 243 x 100 mm" th-14.30 tw=8.78 W = kN/m heam

Answer 1

WF section For A36 steel, allowable bending stress fo= 0.66 fy = 0.66 (250) = 165 MPa M And bending stress due to loading = = 1888 103

For the maximum moment, M mone 1188 X103 = 165 MPa Моме m = 165 x1188 x103 = 19602000 0 Nmm = 196.02 kNm the loading, Now consider WIN lm 9m wla Mman Mmone - = WX (90² = 10.125 w kNm .: 10.125 W = 196.02 w = 19.36 kN, Cincluding self wt) self wt = 658 N/m = 0.658 kN/m .: Maximum external loading that the section can carry = 19.36 -0.658 = 18.702 kN/m
