(a) The rigid bolted connection shown in Figure 4 is used to transmit a total vertical load of 350 kN applied as shown. Two bracket plates are connected to the flanges of the I section using the bolt groups (refer figure 4) and hence, the bolts are loaded in- plane. Determine if the bolted connection shown in Figure 4 can safely support the applied load (use cl. 9.4.1 AS4100 1998). The bolts are M20 of 8.8S grade...

Question 2 (30 marks) The wood beam below (cross section dimensions 150 x 250 mm, as indicated) is strengthened at the bottom using 3 steel reinforcement plates of the same 12mm thickness (see figure), perfectly glued to the wooden beam. The modulus of elasticity for wood is E,-12 GPa and for steel E,-200 GPa. Given the allowable stresses (in both tension and compression) for wood ơw-12 MPa and for steel Ơs = 150 MPa, determine the largest possible moment due...

Standard design practice, as exhibited by the solutions to Probs. 8-66 to 8-70, is to assume that the bolts, or rivets, share the shear equally. For many situations, such an assumption may lead to an unsafe design. Consider the yoke bracket of Prob. 8-61, for example. Suppose this bracket is bolted to a wide-flange column with the centerline through the two bolts in the vertical direction. A vertical load through the yoke-pin hole at distance B from the column flange...
