Situation 5 - The steel strut transmits a compressive force P = 75 kN as shown in the figure. The strut has a hallow cross section with a thickness of 12 mm, and the angle 0 between the strut and the horizontal plane is 45°. An 18-mm-diameter pin through the strut transmits the compressive force to two gussets that are welded to the base plate. Four 20-mm-diameter bolts anchors the plate to concrete. The thickness of the gusset is 16 mm and the thickness of the base plate is 16 mm. Calculate the following: 19. The shearing stress (MPa) in the anchor bolts. A. 65.9 C. 52.1 D. 42.2 Strut Gusset Base plate Pin instruction Strut B. 27.1 20. The bearing stress (MPa) between the pin and the gusset. A. 146.5 C. 195.3 B. 130.2 D. 176.3 21. The bearing stress (MPa) between the anchor bolts and the base plate. A. 41.4 C. 65.3 B. 36.8 D. 74.5
