Figure 1 shows a bolted truss connection used in the construction of a roof system for a large industrial building. The diagonal members of the truss are 150 x 150 x 12 Equal Angies (Grade 300). They are bolted to a 16 mm gusset plate using 8 M20 Grade 8.8/S bolts. a) What is the axial tension design capacity of the connection? (Assume that the 16 mm gusset plate is the strongest component and will not fail) (12 Marks) b)...
Chapter 4, Reserve Problem 018 Three bolts are used in the connection shown in the figure. The thickness of plate (1) is 20 mm. The ultimate shear strength of the bolts is 385 MPa, and the ultimate bearing strength of plate (1) is 385 MPa. Determine the minimum bolt diameter required to support an applied load of P = 180 KN if a minimum factor of safety of 2.5 is required with respect to both bolt shear and plate bearing...
