7.2 Figure 7.34 shows a bracket type of connection is designed to carry a 500kN point load. Assuming all steels of grade S275 steel, the edge distance is 40mm and the thickness of the end-plate is 12mm thick. Design the connection for the following cases: - a) Check the adequacy of the connection if the size of the bolt is M20 of grade 8.8. b) If the size of the bolt is M24 of grade 8.8 and no bolt is installed at the second top row of the connection, check the adequacy of the connection. 275mm This bolt row is P-500kN not installed in question b) L 11 09 DS 420mm III 12 no of bolt for part a) and 10 no. for part b) End-plate + 305x305x97UC Figure 7.34 Bolted bracket
