Two 8 mm & one 12 mm thick S275 plates, shown in Figure Q2, are connected by two 20 mm diameter Grade 8.8 black bolts. Assuming the bolt is fully threaded and all edges are either rolled or machine flame cut. [Use the British Standards steel design Manual BS5950] Design: (ii) (iii) The maximum width of the plates. The minimum overlap length between the two plates. The suitable 6 mm side fillet weld to transmit a 75 kN axial force. If the bolt connection is replaced by a welding connection. Assume the electrode classification to be 35. Determine: (iii) The bolt shear capacity. (iv) The plate bearing capacity. Figure Q2 8 mm 12 mm 8 mm
