SITUATION: The beam in Figure RGM 4.31 is fabricated by attaching a C180x14.6 channel to a W250x17.9 shape with 15-mm-dia rivets. The maximum shear force in the beam is 65 kN. Given properties: C180x14.6: A = 1850 mm^2; d = 178 mm; xcg= 13.8 mm Iy = 0.405x10^6 mm^4; tw = 5.3 mm; tf = 9.3 mm W250x17.9: A = 2270 mm^2; d = 251 mm; Ix = 22.4x10^6 mm^4; tw = 4.8 mm; tf = 5.3 mm 4. Find the maximum allowable spacing (mm) of the rivets if the working stress for a rivet is 100 MPa in shear. A. 140 C. 180 B. 160 D. 200 5. What is the corresponding maximum bearing stress (MPa) exerted by the rivets? A. 245 C. 222 B. 127 D. 186 6. If the rivets are spaced 100 mm on centers, calculate the resulting bearing stress (MPa) in the members connected. A. 132 C. 144 B. 138 D. 150 Thanks for watching!
