SITUATION: The combination section shown consists of a wide flange and a channel. Properties of each section: W600x125 C300x31 A = 15,935 mm2 A = 3892 mm2 d = 610 mm d = 300 mm tw = 12 mm tw = 7 mm bf = 229 mm bf = 75 mm tf = 20 mm tf = 13 mm Ix = 986 x 106 mm4 Ix = 53.7 x 106 mm4 Iy = 39 x 106 mm4 Iy = 1.6 x 106 mm4 x = 18 mm The beam is subjected to a uniformly distributed load (beam weight included) of 20 kN/m throughout the simply supported span of 8 m and a moving load P, in kN. 1. Calculate the resisting moment (kN-m) of the combination section if the allowable flexural stress is Fbx = 186 MPa. A. 644.6 C. 628.6 B. 456.2 D. 720.2 2. Calculate the load P (kN) such that the allowable bending stress is Fbx = 186 MPa. A. 189.4 C. 242.3 B. 221.2 D. 286.6 3. If the wide flange and the channel were joined by 2-20 mm diameter rivets spaced at 150 mm on center longitudinally throughout its length, calculate the allowable load P (kN) if the allowable shear stress in the rivets is Fv = 100 MPa.
